A black body has maximum wavelength 1 m at 2000 K. Its corresponding wavelength at 3000 K will be

$\frac{3}{2} \lambda m$

$\frac{2}{3} \lambda m$

$\frac{16}{81} \lambda m$

$\frac{81}{16} \lambda m$

Answer

$\frac{2}{3} \lambda m$

Explanation

According to Wein's law,
$\lambda T = \, \, \, constant$
$\therefore \, \, \, \, {\lambda }' = (2/3) {\lambda }^m$
