For a body emitting blackbody radiation,the total power emitted is proportional to the 4th power of the body's absolute temperature: (T in kelvins)
and the wavelength of the emitted EM radiation that has the highest intensity is inversely proportional to the body's absolute temperature according to: ( in meters,T in kelvins)
Assume an object is emitting blackbody radiation.
-A body in a room at 300 K is heated to 3,000 K.The wavelength of the most intense EM radiation emitted by the body at 3,000 K is 10 times the wavelength of the most intense EM radiation at 300 K.

Quizplus · Accepted Answer

According to Wien's Law, the wavelength of the most intense radiation is inversely proportional to the temperature. Therefore, if the temperature increases by a factor of 10, the wavelength decreases by a factor of 10, not increases.

For a Body Emitting Blackbody Radiation,the Total Power Emitted Is
