Question

The maximum in the energy distribution spectrum of the sun is at $4753A$ and its temperature is $6050K$. The temperature of the star in K whose energy distribution shows a maximum at $9506A$ is $X\times 605$.Then the value of X is;

Answer 1

Wien's displacement Law:
${\lambda }_{m}T=constant$
${{\lambda }_1}_m{T}_1={{\lambda }_2}_m{T}_2$
$\therefore 4753\ast 6050=9506\ast T_2$
$\Rightarrow T_2={3025}^{0}K$
