Question

which statement correctly describes the relationship between a blackbody radiator, its temperature, and the electromagnetic radiation it gives off? a. as the blackbody radiator becomes warmer, it emits light of shorter wavelengths. b. as the blackbody radiator becomes warmer, it reflects different wavelengths of light. c. as the blackbody radiator becomes cooler, it emits light of shorter wavelengths. d. as the blackbody radiator becomes warmer, it emits random wavelengths of light.

Explanation:

According to Wien's displacement law, the peak wavelength of the radiation emitted by a black - body radiator is inversely proportional to its temperature. As the temperature (warmer) increases, the peak wavelength decreases (shorter wavelengths). Black - body radiators emit radiation (not reflect). And the relationship is not random.

Answer:

A. As the blackbody radiator becomes warmer, it emits light of shorter wavelengths.
