Expert Answer
Max Plank in 1901 , gave a new revolutionary theory known as Quantum theory of radiation.
Main features of this theory are :
- radiant energy is not emitted or absorbed continously but discontinously in the form of small packets of energy called Quanta. Each quanta is associated with a definite amount of energy .
- E is directly proportional to frequency of light,
3. The total amount of energy emitted or absorbed by the body will be some whole no. multiple of quantum ,i.e,
E=nh? , where n is an integer such as 1, 2, 3, ....
we know that ??=c so the equation for energy emitted or absorbed becomes
E=h?/?
