Solution
The four laws of radiation are:
- Kirchoff’s Law - At a given temperature the ratio of emissive power to absorptive power of a blackbody is a constant and is equal to the emissive power of a blackbody at the same temperature.
- Stefan-Boltzman’s Law - The total radiant energy emitted from a body is proportional to the fourth power of the absolute temperature.
- Planck’s Law - It states that the total electromagnetic radiation emitted by a body is not emitted continuously but is made up of discrete units or quanta of energy.
- Wein’s Displacement Law - It states that the blackbody radiation curve for different temperatures will have different peaks at different wavelengths inversely proportional to temperature.
