According to Stefan's law, the total radiation from a black body per second per unit area is proportional to
A. Absolute temperature
B. T2
C. T5
D. T
Answer: Option D
Solution(By Examveda Team)
The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature.Specifically, the Stefan–Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time is directly proportional to the fourth power of the black body's temperature.
