The amount of radiation emitted by a perfectly black body is proportional to
Text Solution
Verified by ExpertsThe correct answer is:
C
According to the Stefan's law the radiant energy emitted by a perfectly black body per unit area per second is directly proportional to the fourth power of its absolute temperature
$R \propto T^{4}$
or $R = \sigma T^{4}$
where $\bar{\sigma}$ is a Stefan's constant
