The radiation of a reference blackbody peaks at a frequency of $500 \times 10 ^ { 15 }$ Hz. If a second blackbody has a peak radiation at half that frequency, its temperature is (compared to that of the reference body)

Question

Quizplus · Accepted Answer

According to Wien's displacement law, the peak frequency of radiation from a blackbody is directly proportional to its temperature. Therefore, if the peak radiation frequency of the second blackbody is half that of the reference, its temperature must also be half as great.

The Radiation of a Reference Blackbody Peaks at a Frequency 500×1015500 \times 10 ^ { 15 }500×1015

The Radiation of a Reference Blackbody Peaks at a Frequency $500 \times 10 ^ { 15 }$
