Question

which phrase describes blackbody radiation? a. radiation that is absorbed by an object as it warms b. radiation that explains the wave model of light c. light given off by an object based on its color d. light given off by an object based on its temperature

Explanation:

Black - body radiation is the thermal electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, or emitted by a black body (an opaque, non - reflective body). It is light given off by an object based on its temperature. Option A refers to absorbed radiation, not emitted as in black - body radiation. Option B is about the wave model of light in general and not specific to black - body radiation. Option C is related to color - based light emission which is not the definition of black - body radiation.

Answer:

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