Experimental investigation show that the intensity of solar radiation is maximum for a wavelength 480 nm in the visible region. Estimate the surface temperature of sun. Given Wien's constant b = $2.88 \times 10^{- 3}$ m K.

Open in App

Solution

We know that-

$λ T = b$

$⟹ T = \frac{b}{λ}$

$⟹ T = \frac{2.88 \times 10^{- 3}}{480 \times 10^{- 9}}$

$⟹ T = 6000 K$
