Question
Differentiate the following:
- Wave velocity and particle velocity.
- Harmonics and overtones.
| Wave velocity | Particle velocity |
| The velocity of wave motion through a particular medium is constant. It depends only on the nature of the medium, does not depends upon its frequency or wavelength or intensity. | Velocity of the particles during their vibration is different at different position. |
| Harmonics | Overtones |
| Harmonics are the notes/ seconds of frequency equal to or an integral multiple of fundamental frequency (n). Thus, first, second, third, ... harmonics have frequencies n, 2n, 3n, ... respectively. | Overtones are the notes/ seconds of frequency twice/ thrice/ four times ... the fundamental frequency (n). Thus, first, second, third, ... overtones have frequencies 2n, 3n, 4n, ... respectively and so on. |
