Question
Write basic conditions for formation of stationary waves.
✓
Answer
The basic conditions for formation of stationary waves are listed below:
- The direct and reflected waves must be travelling along the same line.
- For stationary wave formation, the superposing waves should either be longitudinal or transverse. A longitudinal and a transverse wave cannot superposition.
- For formation of stationary waves, there should not be any relative motion between the medium and oppositely travelling waves.
- Amplitude and period of the superposing waves should be same.
