Solar radiation is found to have an intensity maximum near the wavelength range of `470 nm`. Assuming the surface of sun to be perfectly absorbing `(a =1)`, calculate the temperature of solar surface.

Text Solution

Verified by Experts

Since `a = 1`, sun can be assumed to be emitting as a black body from Wien's law for a black body
`lambda_(m) T = b`
`rArr T = (b)/(lambda_(m)) = (0.282(cm-K))/((470xx10^(-7)cm))`
`~~ 6000K`.
