What are stationary waves? Why are they called stationary waves?
Advertisements
उत्तर
- When two identical waves travelling along the same path in opposite directions interfere with each other, the resultant wave is called a stationary wave.
- Stationary waves are called so because the resultant harmonic disturbance of the particles does not travel in any direction and there is no transport of energy.
