Question

The wavelength corresponding to maximum emission of solar radiation is

• A. $8000\dot{A}$
• B. $4753\dot{A}$
• C. $457\dot{A}$
• D. $753\dot{A}$

Answer 1

The correct option is B $4753\dot{A}$

The average temperature of the sun is 5800K
According to Wein's displacement law:
$\lambda T=b=2.88\times {10}^{-3}mK$
i.e.
$\lambda =\frac{b}{T}=\frac{2.88\times {10}^{-3}}{5800}=4827\dot{A}$
Option B is correct.
