Question

which phrase describes blackbody radiation?a. light given off by an object based on its colorb. radiation that is absorbed by an object as it warmsc. radiation that explains the wave model of lightd. light given off by an object based on its temperature

Explanation:

Blackbody radiation is the electromagnetic radiation emitted by a perfect blackbody (an object that absorbs all incident electromagnetic radiation). The spectrum of blackbody radiation depends only on the temperature of the blackbody. It is not related to the color of the object (so A is wrong). Blackbody radiation is about emission, not absorption (so B is wrong). Blackbody radiation was one of the phenomena that led to the development of the quantum theory of light (not directly explaining the wave - model of light, so C is wrong).

Answer:

D. Light given off by an object based on its temperature
