Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

Properties :

1.Electromagnetic waves are propagated by oscillating electric and magnetic fields oscillating at right angles to each other.

2.Electromagnetic waves travel with a constant velocity of  3 x 108 ms-1 in vacuum.

3.Electromagnetic waves are not deflected by electric or magnetic field.

4.Electromagnetic waves can show interference or diffraction.

5.Electromagnetic waves are transverse waves.

6.Electromagnetic waves may be polarized.
