-
The wavelength at which the peak of intensity of blackbody radiation occurs
-
- increases with increase in temperature
- decreases with increase in temperature
- is the same at all temperatures
- does not follow any pattern as temperature changes
- increases with increase in temperature
Correct Option: B
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.
