Find the temperature of a black body if its spectrum has a peak at :- `lambda_max` = 3 cm (microwaves region)

Find the temperature of a black body if its spectrum has a peak at :- lambda_max = 700 nm (visible)

The power radiated by a black body is P, and it radiates maximum energy around the wavelength lambda_(0) . If the temperature of the black body is now changed so that it radiates maximum energy around a wavelength 3lambda_(0)//4 , the power radiated by it will increase by a factor of

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 3 lamda_0//4 . The power radiated by the black body will now increase by a factor of

Earth's mean temperature can be assumed to be 280K. How will the curve of blackbody radiation look like for this temperature? Find out lambda_max , in which part of the electromagnetic spectrum, does this value lie?

The surface temperature of a black body is 1200 K. What is the wavelength corresponding to maximum intensity of emission of radiation if Wien's constant b = 2.892 xx 10^-3 mk ?

When a body has the same temperature as that of its surroundings
