A surface with an albedo of 1 means that
A surface with an albedo of 1 means that it reflects all incoming solar radiation, scattering it back into space. Albedo is a measure of how much light is reflected by a surface relative to the total amount of light that hits it.
To determine the albedo of a surface, you would typically use instruments like radiometers or spectrometers to measure the amount of incoming solar radiation and the amount that is reflected by the surface. By comparing these measurements, you can calculate the albedo using the following formula:
Albedo = Reflected radiation / Incident radiation
A value of 1 for albedo indicates that all of the incident solar radiation is being reflected back, resulting in no absorption or transmission of light by the surface. This means that the surface appears very bright because it reflects all colors of light equally.
Examples of surfaces with high albedo include freshly fallen snow, ice, and some types of clouds. These surfaces reflect a significant amount of solar radiation and therefore have a high albedo.
