Which of the following has the highest albedo relative to visible light )?

The highest albedo relative to visible light is snow. Albedo, often referred to as reflectivity, is the fraction of visible light that is reflected from a surface back into the atmosphere. It is often expressed as a percentage.

Snow typically has an albedo of between 70-90%, whereas the average for other surfaces, such as grass and soil, is nearer to 10-20%. Reflection of light off a snowy surface is the reason it is able to stay so brightly white in sunshine, and why it appears brighter than if there were no snow present.

The presence of snow generally leads to cooler temperatures, as it acts as a large reflector of incoming solar radiation. Snow is also sometimes referred to as a ‘global reflector’ due to its ability to reflect energy and heat back into the atmosphere.

Which has highest albedo?

Albedo is the measure of a surface’s ability to reflect light. The surfaces with the highest albedo are usually those that are extremely reflective, such as snow, ice, certain types of clouds, and certain minerals such as mica.

Snow and ice have the highest albedo values, reflecting an average of 80-90% of solar radiation. Clouds also have high albedo values and usually reflect between 20-90% of solar radiation, depending on the cloud composition and height.

Certain cloud types can even reflect more than 90% of solar radiation, due to the formation of ice crystals. In addition to these natural surfaces, man-made surfaces such as roofing materials and reflective paint also have relatively high albedo values, often reflecting between 50-80% of solar radiation.

Where is Earth’s albedo highest?

The Earth’s albedo is highest in the tropics, where the sun is at its most intense. In the tropics, the albedo of the land surface can rise to 0. 9, while in other parts of the world, it can be much lower.

In these regions, the albedo of the atmosphere is usually higher, and can reach values as high as 0. 8. This is due to the fact that in the tropics, more heat is reflected back into space due to the presence of more clouds.

As clouds have higher reflective properties than the surface of the Earth, more of the incoming solar radiation is reflected back out into space, rather than being absorbed by the Earth’s surface. Thus, the Earth’s albedo is highest in the tropics.

What has a higher albedo white or black?

The albedo of a surface is a measure of how much incoming light it reflects. Generally, a surface that is white or very light in color tends to have a higher albedo than a surface that is black or very dark in color.

This is because white is more reflective, whereas black absorbs more light. White surfaces reflect more of the sun’s energy from all directions, which results in a higher albedo, meaning less energy is absorbed.

Meanwhile, black surfaces absorb more of the sun’s energy, thereby lowering the albedo and increasing the amount of energy that is retained. In addition, darker surfaces and colors also absorb more heat from direct sunlight, resulting in higher temperatures than lighter surfaces.

Thus, white has a higher albedo than black.

Which of the following types of clouds has the highest albedo?

The type of cloud that has the highest albedo is a stratus cloud. Stratus clouds are low-level clouds consisting of a single layer of water droplets or ice crystals that appear flat, featureless, and always below 6,500 feet in the atmosphere.

The flat shape of stratus clouds creates an abundance of surfaces for the sun’s energy to reflect off of, so they have a very high albedo of about 0. 75 (the albedo of a perfectly reflective surface is 1).

By comparison, cumulus clouds have an albedo of 0. 45 and cirrus clouds have an albedo of around 0. 1. Albedo is the percentage of incident radiation reflected from the surface of a non-reflective material, such as clouds.

A higher albedo means more energy is bounced back into space, preventing it from being absorbed by the Earth.

What climate has lowest albedo?

Albedo is a measure of how much a surface reflects the sun’s energy. Dark surfaces have a low albedo, while highly reflective surfaces have a high albedo. Generally, warmer climates have a lower albedo than cooler climates.

Desert surfaces have the lowest albedo of all climates because they are usually covered in dark, absorptive sand and soil. Heat from the direct sunlight is easily absorbed into the ground, which can lead to higher temperatures.

So, while the climate of a desert may be hot and dry, it usually has the lowest albedo of all climates.

Where is low albedo found?

Low albedo can usually be found in dark, non-reflective surfaces. These surfaces tend to absorb sunlight rather than reflect it, so they appear darker in color. Examples of low albedo materials include charcoal, asphalt, black soils, and almost all dark colored rocks.

In some cases, even darker shades of vegetation can have a low albedo. For example, deep black swamps, oceans and forests of old growth trees can have a low albedo. On a planetary scale, low albedo materials can be found on moons and asteroids, which are largely composed of dark and non-reflective materials.

Low albedo can also be found on the surface of planets and moons that have dark shading due to their volcanic or geological history. On Earth, low albedo materials are most prevalent in polar regions, where snow and ice accumulate.

What is an example of low albedo?

Low albedo is a measure of how much light an object reflects when it’s hit by sunlight. An example of low albedo would be asphalt pavement, which has a reflection of only 4-7%. This is because asphalt absorbs most of the light instead of reflecting it back out.

Dark colored and matte surfaces generally have lower albedo, as do objects with a lot of surface texture or curves. Other examples of low albedo surfaces include forests, soil, and water bodies which have a reflection of approximately 10-15%.

Arctic ice has a low albedo of approximately 45%. The lowest albedo of all is the moon, which has a reflection of only 7%.

What is albedo Where is it Highest Lowest?

Albedo is a term used to describe the amount of sunlight that a surface reflects back into space. The less sunlight a surface reflects, the more it absorbs into the surface, making it warm. The higher the albedo, the more sunlight is reflected back into space, so a higher albedo means that the surface is cooler.

The albedo of a surface can range from 0 – 1. Anything with an albedo of 0 is a complete absorber, meaning the surface absorbs all of the light it receives. On the other end, a surface with an albedo of 1 is a perfect reflector, meaning it reflects all of the light that it receives.

Different types of surfaces have different albedos. For instance, snow and ice are surfaces which have a high albedo and therefore reflect the majority of the sunlight that reaches them, making them cooler.

On the other hand, dark surfaces such as soil and vegetation absorb more light, making them warmer. As a result, these surfaces have a lower albedo.

Generally speaking, the highest albedos are found in the polar regions where there is a large amount of snow and ice. On the opposite end, the lowest albedos are found in the tropics where there are usually darker surfaces including soil and vegetation.

What is the lowest albedo of a natural surface?

The lowest albedo of a natural surface is likely soil, with an albedo of 0. 08-0. 12. This means that only 8-12% of the light that falls on it is reflected back into the atmosphere. Other very low albedo natural surfaces include water, with an albedo of 0.

06-0. 09, and surfaces covered in snow or ice, with an albedo of 0. 3-0. 4. Surfaces covered with dark vegetation can also have a very low albedo, as low as 0. 03-0. 1. While certain building materials, such as concrete, can have an even lower albedo, they are not natural surfaces and should not be considered when discussing the lowest albedo of a natural surface.

Is high albedo hot or cold?

High albedo means that an object reflects more solar radiation than it absorbs, so it is generally considered to be a cooling process. The concept is related to the greenhouse effect, in which light from the sun is absorbed, raising the temperature of an enclosed space.

High albedo works to reduce the amount of solar radiation absorbed, and thus maintain a cooler temperature than without high albedo. In terms of a surface, high albedo materials, such as snow, ice, rock, and sand, can help remain cooler.

On the other hand, low albedo materials, such as asphalt, absorb more solar radiation and get hotter. This is why it is so much hotter to walk on the asphalt in the summer when directly compared to walking on snow in the winter.

What surface absorbs the highest percentage of incident solar radiation at noon?

At noon, the surface that absorbs the highest percentage of incident solar radiation is generally a dark surface. Dark surfaces absorb more of the incident solar radiation because they are poor reflectors and have a high albedo (the ratio of reflected to incident solar radiation).

Dark surfaces can range from black glass, black paint, or even dark natural materials such as asphalt, soil, or rock. Additionally, the surfaces should be kept free from dust and moisture and be positioned in full sun to maximize their absorption efficiency.

Which surface absorbs more energy from radiation?

The surface that absorbs more energy from radiation is the one having greater absorbed solar energy (ASR). This energy is determined by the amount of solar radiation that a surface reflects, absorbs and re-emits.

A surface reflects solar radiation in different proportions, depending on the material and color of the surface. Materials that have dark colors absorb more sunlight than lighter ones and warm more quickly.

Therefore, the darker the surface, the more energy it will absorb from radiation. Generally, water surfaces absorb more solar energy due to their dark color and high reflectivity, while other materials such as asphalt and concrete, which generally have low reflectivity and light color, absorb less energy.

Which absorbs the most solar radiation energy coming from the Sun?

The Earth’s atmosphere absorbs most of the energy coming from the Sun. Even though a lot of the energy is reflected back into space, most of it is absorbed by the atmosphere and some of it is absorbed by the Earth’s surface.

This energy is then trapped by greenhouse gases, like Carbon Dioxide, which can make the surface and the atmosphere warmer. The solar energy that is absorbed by the atmosphere is responsible for the winds and ocean currents we experience on our planet, as well as the climate regimes.

In other words, the atmosphere absorbs more solar radiation energy than the Earth’s surface, and plays a very important role in regulating the climate of the planet.

Which type of surface absorbs the greatest amount of electromagnetic energy from the Sun?

The type of surface that absorbs the greatest amount of electromagnetic energy from the Sun is dark, non-reflective surfaces. Any surface that is dark in color, such as black, dark blue, and dark green, absorb more energy from the Sun than lighter colored surfaces, such as white and light gray.

Dark surfaces are also typically non-reflective, which allows them to absorb more of the Sun’s energy instead of reflecting it back away. Dark surfaces also tend to have high emissivity ratings, which means they convert more of the Sun’s energy into thermal energy.

Additionally, dark surfaces typically have a low albedo rating, meaning they are able to absorb more of the Sun’s energy and reflect less of it away.
