The wavelengths of radiation that an object emits depend primarily on the object's ____.
A) temperature
B) photons
C) density
D) reflective surfaces

Question

Quizplus · Accepted Answer

The wavelength of radiation emitted by an object is directly proportional to its temperature. This is known as Wien's law, which states that the wavelength of maximum intensity of radiation emitted by a black body is inversely proportional to its temperature. Therefore, an object's temperature is the primary factor that determines the wavelength of radiation it emits.
