When two waves of same frequency, wavelength and amplitude travel in opposite direction at same speed, their superposition give rise to a new type of wave which is known as standing or stationary waves.
Energy does not propagate in this type of waves. Hence, it is named as stationary waves.
Stationary waves are of two types,
- Transverse stationary waves
- Longitudinal stationary waves
Transverse stationary wave: It is produced in,
- Stretched string
- Sonometer
Longitudinal stationary wave: It is produced in,
- Organ pipe
- Resonance tube
