Question 12 • SC332 Environmental Science B

Which statement best describes the effect of texture on absorption of radiant energy?

Answer
A
Rough and smooth surfaces do not absorb energy.
B
Rough and smooth surfaces affect the absorption equally.
C
Rough surfaces absorb more energy than smooth surfaces.
D
Rough surfaces absorb less energy than smooth surfaces.

Explanation

Rough surfaces tend to reflect radiant energy in many directions, so less of it is reflected straight back and more is absorbed. Smooth surfaces, especially shiny ones, reflect more radiant energy. Therefore, rough surfaces absorb more energy than smooth surfaces.
