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`).

Options

A. 4000K
B. 6000K
C. 8000K
D. `10^(6)K`

Answer

B

Explanation

According to Wien.s displacement law, `lamda_("max") T=B` wher b is the Wien.s constant.
`:. T= (b)/(lamda_("max")) = (2.88 xx 10^(-3)mK)/(480 xx 10^(-9)m) = 6000K`
