The wavelength of maximum emission shifts towards smaller wavelengths as the temperature of black body

The wavelength of radiation of maximum intensity is lamda when the temperature of a body is 2000 K . If now temperature is raised to 4000 K . the wavelength of radiation of maximum intensity will be

The wavelength of maximum emitted energy of a body at 700K is 4.08 um . If the temperature of the body is raised to 1400 K, the wavelength of maximum emitted energy will be

(A) : For higher temperature, the peak emission wavelength of a black body shifts to lower wavelengths. ( R) : Peak emission wavelength of a blackbody is proportional to the fourth power of absolute temperature.

Two identical bodies of emissivities 0.01 and 0.16 and at different temperature emit the same rate of radiation but with a difference of wavelength of maximum emission of 1 micron. The wavelengths of maximum emission of the two bodies are (in microns)

A black body radiates power P and maximum energy is radiated by it at a wavelength lamda_(0) . The temperature of the black body is now so changed that it radiates maximum energy at the wavelength (3lamda_(0))/4 . What is the power radiated by it at the new temperature ?

The energy spectrum of a black body exhibits a maximum around a wavelength lamda_(0) , the temperature of the black body is now changed such that the energy is maximum around a wavelength 3lamda_(0)//4 . The power radiated by the black body will now increase by a factor of
