Question

The spectral energy distribution of the sun (temperature 6050 K) is maximum at 4753 $A^{\circ }$. The temperature of a star for which this maximum is at 9506 $A^{\circ }$ is

• A. 6050 K
• B. 3025 K
• C. 12100 K
• D. 24200 k

Answer 1

Answer: (B)

3025 K

From wein's displacemt law,we know that, $\lambda T=constant$
So,${\lambda }_1{T}_1={\lambda }_2{T}_2$
So, $T_2=\frac{{\lambda }_1{T}_1}{{\lambda }_2}=\frac{6050\times 4753}{9506}=3025K$
