Question

List the properties of electromagnetic waves.

Answer 1

Electromagnetic waves are composed oscillating electric and magnetic field at right angles to each other.

Properties

1. Electromagnetic waves are propagated by oscillating electric fields and magnetic field oscillation at right angles to each other.
2. These waves travel with speed $3\times {10}^{8}m{s}^{-1}$ in vacuum.
3. They are not deflected by electric or magnetic field.
4. They can show interference or diffraction.
5. They are transverse waves.
6. May be polarized.
7. Need no medium of propagation.
8. wavelength and frequency related as $c=v\lambda$.
