During blackbody radiation at a constant wavelength, intensity of radiation ___________ with increase in temperature.
At a constant wavelength (I2>I1) with increase in temperature which shows that at higher temperature, intensity is high.
A black body emits radiations of maximum intensity at a wavelength of 5000˙A , when the temperature of the body is 12270 C. If the temperature of the body is increased by 1000° C, the maximum intensity of emitted radiation would be observed at
