Albedo is ameasure of how much of the Sun's light is reflected by a planet. Light is an example of EM radiation.
Radiation sickness is caused only by EM radiation of the ionising sort, which is UV, x-rays, gamma rays and the like, well above the spectrum of radio waves and light.
Surfaces with high albedo reflect more solar radiation, while surfaces with low albedo absorb more solar radiation.
Surfaces with low albedo absorb more solar radiation and reflect less, while surfaces with high albedo reflect more solar radiation and absorb less.
This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
Albedo is the proportion of light that an object reflects.
Albedo means how reflective the earth is. Snow increases the earth's albedo by reflecting more of the sun's radiation.
Albedo refers to the reflectivity of a surface. Surfaces with high albedo reflect more solar radiation back into space, which can cool the Earth's surface and lower temperatures. Surfaces with low albedo absorb more solar radiation, leading to warming of the Earth's surface.
A higher albedo means that more of the incident radiation is reflected, and less of it is absorbed.
The lowest albedo is associated with surfaces that absorb most of the incoming sunlight, reflecting very little. For example, asphalt has an albedo of around 0.05 to 0.10, meaning it reflects only 5% to 10% of sunlight. Other surfaces with low albedo include forests and oceans, which also absorb significant amounts of solar radiation.
The albedo of the Earth's surface is the fraction of solar radiation that is reflected back into space. It is a measure of how reflective a surface is, with higher albedo values indicating more reflection and less absorption of sunlight by the surface. Land surfaces, ice, and clouds generally have higher albedo values, while oceans and forests have lower albedo values.
Fresh snow, ice, and white sand are examples of surfaces with high albedo. These surfaces reflect a large percentage of incoming solar radiation back into space, resulting in a cooling effect on the surrounding environment.

Earth has an average albedo of about 30%, meaning it reflects about 30% of the incoming solar radiation back into space. This albedo is influenced by various factors like clouds, ice, and land cover.
