The solar radiation spectrum reveals that the intensity coesponding to a wave- length of 4750 `A^(0)` is maximum. Estimate the surface temperature of the sun
(Given Wien 's constant= 2.89`xx 10^(-3)` m-K )

Text Solution

Verified by Experts

From Wien.s displacement law, the temperature T of a body corresponding to maximum intensity wavelength `lambda_(m) ` is given by
`T = (b)/(lambda_(m)) " " therefore T = (2.89 xx 10^(-3) m - K )(4750 xx 10^(-10) m ) = 6084` K
This temperature is corresponding to the chromosphere (surface) of the sun.
