Concept explainers

Wien's displacement law

Students often get confused between Wien's displacement law and Planck's radiation law. Although both are historically related, yet they are conceptually different. Planck's law helps determine the spectrum of a blackbody, while Wien's law determines the relationship between peak wavelength and temperature.

Question

A: pherical body of 2.0 cm diameter is maintained at 500 °C. Assuming that
it radiates as if it is a blackbody, at what rate is energy radiated from the
sphere?
O 35.2 W
O 41 W
O 52 W
Not any of the choices listed
25.5 W
