Questions  

In solar radiation, the intensity of radiation is maximum around the wavelength λ .  If R is the radius of the sun and c is the velocity of light, the mass lost by the sun per second is proportional to     

a
R2λ4c2
b
R2λ2c2
c
R3λ4c3
d
R3λ4c2

detailed solution

Correct option is A

According Stefan’s lawQt=σ4πR2T4=mc2Where m is the mas converted to energy per sec. but  λmT=constantT∝1λm=σ4πR2T4c2∝R2λ4c2
