The "color" or wavelength of maximum emission of radiation for a hot,solid body (or a dense gas such as a star)when the body cools from a temperature of several thousand degrees
A) remains fixed,as the light fades and eventually becomes invisible to the eye.
B) moves toward the red end of the spectrum.
C) moves toward the blue end of the spectrum.
D) remains absolutely constant,depending only on the original color of the body.

Question

Quizplus · Accepted Answer

As a hot, solid body or dense gas cools, its maximum emission of radiation shifts towards the red end of the spectrum. This phenomenon is known as redshift, and it occurs because as the temperature decreases, the average wavelength of the emitted radiation also increases. This is a well-known phenomenon in astrophysics, and it is used to determine the temperature and composition of stars and other celestial objects.
