Concept introduction:
Electromagnetic waves are radiations that are formed by oscillating electric and magnetic fields. The electric and magnetic field components of an electromagnetic wave are perpendicular to each other. The general properties of electromagnetic waves are as follows:
1) Electromagnetic waves travel at the
2) Electromagnetic waves are transverse in nature.
3) Electromagnetic waves may be polarized.
4) Electromagnetic waves are not deflected by electric or magnetic field.
5) Electromagnetic waves need no medium for propagation.
The formula to relate the frequency and wavelength of an electromagnetic radiation is,
