Stationary wave is formed by
-
- a transverse wave superposing a longitudinal wave
- two waves of the same speed superposing
- two waves of same frequency travelling in the same direction
- two waves of same frequency travelling in the opposite direction
- a transverse wave superposing a longitudinal wave
Correct Option: D
Stationary or standing waves are formed in a medium when two waves having equal amplitude and frequency moving in opposite directions along the same line, interfere in a confined space. Generally, such waves are formed by the superposition of a forward wave and the reflected wave. Both longitudinal and transverse types of waves can form a stationary wave.
