The emissivity of a material lies between
A)1 and 2.
B)0 and 100.
C)0 and 1.
D)1 and 10.
E)none of the above.

Question

Quizplus · Accepted Answer

The emissivity of a material refers to its ability to emit thermal radiation. It is a dimensionless value that varies between 0 and 1, where 0 represents a perfect reflector that does not emit any radiation, and 1 represents a perfect emitter that emits radiation at all wavelengths. Therefore, the correct choice is (C) 0 and 1.
