Calculate the temperature of the black body from given graph.

Text Solution

Verified by Experts

The correct Answer is:
`1927K`
By using Wien's displacement law
` T = (b)/(gamma_(m)) = (2.89 xx 10^(-3))/(1.5 xx 10^(-6)) = 1927K`

Calculate the temperature at which a perfect black body radiates at the rate of 1 W cm^(-2) , value of Stefan's constant, sigma = 5.67 xx 10^(-5) W m^(-2) K^(-8)

Statement I: As the temperature of the black body increases, the wavelength at which the spectral intensity (E_lamda) is maximum decreases. Statement II: The wavelength at which the spectral intensity will be maximum for a black body is proportional to the fourth power of its absolute temperature.
