Question

Which one of the following is associated with 'Albedo'?

  1. Transmitting power
  2. Absorbing power
  3. Emissive power
  4. Reflecting power

Answer:

Option D: Reflecting power

Detailed Solution:

The correct answer is “Reflecting power”.

Albedo is a measure of how reflective a surface is.

A surface with high albedo reflects a large portion of the sunlight that strikes it, while a surface with low albedo absorbs most of the sunlight. For example, snow has a high albedo, while dark soil has a low albedo.
