Discuss different types of interference of waves.

Discuss different types of interference of waves.

---

Interference occurs when two waves merge. Such a merger may give rise to three cases:
- A much larger wave is formed i.e. constructive interference.

The waves are in phase and superimpose to produce a wave with a greateramplitude.

- A smaller wave is formed i.e. destructive interference.

The waves are out of phase with a phase difference of 1800. Since they have different amplitudes, they superimpose to form a wave with a smaller amplitude.

- A stationary wave.

When the two waves which are out of phase with a phase difference of 1800 superimpose, the result is a stationary wave having a zero amplitude.
