The wavelength at which the peak of intensity of blackbody radiation occurs

Answer»

 Decreases with increase in temperature



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.
