The amount of radiation emitted by a blackbody depends on all of these properties of the blackbody EXCEPT
A) the wavelength under consideration.
B) the temperature.
C) the chemical composition.
D) the surface area.

Question

Quizplus · Accepted Answer

The amount of radiation emitted by a blackbody is determined by its temperature and surface area, and it varies with wavelength, but it does not depend on the chemical composition of the blackbody. This is because a blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence, and its emission characteristics are solely a function of its temperature.
