The ratio of the total solar radiant energy returned by a planetary body to the total radiant energy incident on the body, the called:
A. Reflectance
B. Reflectance factor
C. Albedo
D. None of these
Answer: Option C
Solution (By Examveda Team)
Albedo is the ratio of the total solar radiant energy returned by a planetary body to the total radiant energy incident on the body.It is a measure of how much light that hits a surface is reflected without being absorbed.
This term is commonly used in the fields of astronomy and remote sensing to describe the reflectivity of planets, moons, and other celestial bodies.
