Power emitted per unit area of a black body is `R " watt/m"^(2)`. At what wavelength will the power radiated by black body be maximum is stefan's constant is `sigma` and Wien's constant is b then.

The power emitted per unit area of a black body is R watt/ m^2 . At what wavelength will the power radiated by the black body be maximum. If the Stefan's constant is sigma and Wien's constant is b, then

If a black body radiating at T = 1650K, at what wavelength is the intensity maximum?

The wavelength of the radiation emitted by a black body is 1 mm and Wien's constant is 3xx10^(-3) mK. Then the temperature of the black body will be

Statement-1 : When temperature of a black body is halved, wavelength corresponding to which energy radiate is maximum become twice. Statement-2 : This is as per Wien's Law.

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 = 2.892xx10^(-3)mK ?

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 ?

The radiations emitted by the sun are analyzeed and the spectral energy distribution curve is plotted. as shown. The radius of the sun is R , the earth is situated a distance 'd' from the sun. Treat the sun as perfectly black body which radiates power at constant rate fill till its store of hydrogen gets exhausted. (Stefan's constant = sigma , Wien's constant =b , speed of light =c ) If the earth is at a distance 'd' from the sun the intensity of light falling on the earth (called solar constant S) is

The quantity of heat radiated per unit time by a perfectly black body at 300 K is 81kJ//s . What is the power radiated by a body of emissivity 0.8 and having the same area as that of the black at 500 K ?
