Solar radiation emitted by the sun resembles that emitted by a black body at a temperature of $6000\, K$. Maximum intensity is emitted at a wavelength of about $4800\,\mathop A\limits^o $. If the sun was cooled down from $6000\, K$ to $3000\, K$, then the peak intensity would occur at a wavelength of ......... $\mathop A\limits^o $

A

$4800$

B

$9600$

C

$2400$

D

$19200$

Solution

$\lambda {m_1}{T_1} = \lambda {m_2}{T_2}$
