Experimental investigations show that the intensity of solar radiation is maximum for a wavelength `480 nm` in the visible ragion. Estimate the surface temperature of sun. (Given Wien's constant `b = 2.88 xx 10^(-3) m K`).

The intensity of the solar radiation is maximum for wavelength lamda_(m)=4753Å in the visible region. The surface temepratureof the sun, is (Assume the sun to be a black body. Wien's constant (b) =2.892xx10^(-3)mK )

Estimate the surface temperature of sun. Given for solar radiations, lambda_(m)=4753Å . ( b=2.89xx10^(-3) meter Kelvin)

The wavelength of maximum intensity of emission of solar radiation is lambda_(m) = 4753Å and from moon it is 14 mm . The surface temperature of sun and moon are: (Given b = 2.898 xx 10^(-3) "metre"// "Kelvin")

Find the wavelength at which a black body radiates maximum energy, if its temperature is 427^(@) C. (Wein's constant b=2.898 xx 10^(-3) mK )

The sun radiates maximum energy at wavelength 4753Å . The surface temperature of the sun if b=2.888xx10^(-3)mK , is

A black body initially at 27^(@)C is heated to 327^(@)C is heated to 327^(@)C . How many times is total heat emitted at the higher temperature than emitted at lower temperature ? What is the wavelength of the maximum energy radiation at the higher temperature ? Wien's constant = 2.898 xx 10^(-3) mK .
