Q961
The wavelength at which the peak of intensity of blackbody radiation occurs
A.
Increases with increase in temperature
B.
Decreases with increase in temperature
AnswerC.
Is the same at all temperatures
D.
Does not follow any pattern as temperature changes
Answer: Option B
Solution
Answer: Option B
Solution:
According to Wien’s displacement law, when the temperature of a blackbody radiator increases, the overall radiated energy increases. Wavelength of maximum emission from a blackbody is inversely proportional to its temperature. Shorter-wavelength (higher-frequency) light corresponds to higher-energy photons.
