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

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.

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.

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

The power radiated by a black body A is E_(A) and the maximum energy radiated was at the wavelength lambda_(A) .The power radiated by another black body B is E_(B) = NE_(A) and the radiated energy was at the maximum wavelength, (3)/(4)lambda_(A) . What is the value of N?

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 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
