Concept Introduction:
A wave is a disturbance or variation that travels through a medium transporting energy without transporting matter. The wavelength is the distance between identical points on successive waves. The frequency is the number of waves that pass through any particular point in 1 second.

Planck’s quantum theory
1. Different atoms and molecules can emit or absorb energy in discreet quantities only. The smallest amount of energy that can be emitted or absorbed in the form of electromagnetic radiation is known as quantum.
2. The energy of the radiation absorbed or emitted is directly proportional to the frequency of the radiation. The energy of radiation is expressed in terms of frequency as,
E = hν
Where,
E = energy of the radiation
h = Planck’s constant (6.626×10–34 Js)
ν = Frequency of radiation
Substituting the frequency formula in this equation,
