Antinodes Positions on a standing wave where there is a maximum displacement.
| Standing Waves | Progressive Waves | |
|---|---|---|
| Amplitude | Maximum at antinode and zero at nodes | The same for all parts of the wave |
| Frequency | All parts of the wave have the same frequency | All parts of the wave have the same frequency |
| Wavelength | Twice the distance between adjacent nodes | The distance between two adjacent peaks |
| Phase | All points between two adjacent nodes in phase | Points one wavelength apart in phase |
| Energy | No energy translation | Energy translation in the direction of the wave |
| Waveform | Does not move forward | Moves forwards |
