- Stationary wave is also known as the standing wave.
- It is a combination of two waves, with the same amplitude and the same frequency, moving in the opposite direction.
- A wave that travels in a medium with the same amplitude in the same direction is called a traveling wave or a progressive wave.
EXPLANATION:
- Difference between Progressive wave and standing stationary wave:
| Stationary wave | Progressive wave | |
| Energy and Momentum | no net transfer in energy and momentum | both move with speed c=f × λ |
| Frequency | All particles oscillate at the frequency except node | all particles move with the same frequency |
| Amplitude | it varies from zero at nodes to maximum at the antinode | it is the same for all particles |
| Phase Difference | all particles between nodes are at the same phase difference | any two particles have a phase difference equal to \(\frac{2 \pi d}{\lambda}\) where d is the distance between two particles |
