The spectral energy distribution of star is maximum at twice temperature as that of sun. The total energy radiated by star is
Text Solution
Verified by ExpertsThe correct answer is:
C
From Stefan's law of radiation, the total radiant energy emitted per second per unit surface area of a black body is proportional to the fourth power of the absolute temperature 
of the body.
Therefore, 
where 
is Stefan's constant.
Given, 
Hence, total energy radiated by star is sixteen times as that of the sun.
