Why does a good absorber of radiant energy appear black?
To Describe: An absorber of a radiant energy appears black.
Answer to Problem 14A
A black body is a good absorber as it does not allow any large reflection of incident light.
Explanation of Solution
Introduction:
A black body is a good absorber than any other substance and so it can absorb the heat faster. It can absorb radiation of all wavelengths for all the angles if incidence. There is a very small amount of reflection from a black body.
An absorber of a radiant energy appears black due to the property of black body substance which enables it to absorb all electromagnetic radiation incident at any angle.
Conclusion:
Hence, a black body is a good absorber.
