The maximum energy is the thermal radiation from a hot source occurs at a wavelength of 11 xx 10^(-5) cm . According to Wien’s law, the temperature of this source (on Kelvin scale) will be n times the temperature of another source (on Kelvin scale) for which the wavelength at maximum energy is 5.5 xx 10^(-5) cm. The value of n is:

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 ?

Interference pattern is obtained with a source of red light of wavelength 6400 Å. The source is then replaced by another source of wavelength 4000 Å. It is found that nth bright fringe of first source coincides with ( n + 3 ) ^( th ) bright finge of second source. The order of finge is equal to

Solar radiation emitted by the sun resembles the radiations emitted by a black body at the temprature of 6000 K. Maximum intensity is emitted at a wavelength of 4800 Å. If the temperature of the sun decreases from 6000 K to 4000 K , then the peak intensity would occur at a wavelength of

The wavelength of maximum energy distribution by a star A is 4500 Å at a temperature of 5000 K. Calculate the temperature of star B for which wavelength of maximum energy distribution is 8000 Å.

A black body radiated maximum energy around a particular wavelength at a given temperature. If the temperature of the black body is now changed so that it radiates maximum energy around a wavelength n time the original wavelength (n lt 1) then power radiate by it will increases by a factor of:
