The solar radiation spectrum reveals that the intensity corresponding to a wavelength of `4750Å` is maximum Estimate the surface temperature of the sun.
(given wien's cosntant`=2.89xx10^-3m-K`)

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`.
