Two spherical stars A and B emit blackbody radiation. The radius of A is 400 times that of B and A emits 10 4 times the power emitted from B. The ratio 
of their wavelengths λ A and λ B at which the peaks occur in their respective radiation curves is:
Text Solution
Verified by ExpertsThe correct answer is:
B
According to Wien's displacement law
TA = 
Ratio of energy radiated per unit time
= 10 4
⇒ 
= 2 4
⇒ 
= 2
