| Summary |
|
 WAVE is a form of disturbance, which travels through a material medium due to the repeated periodic motion of the particles of the medium about their position. |
| |
|
Mechanical wave is a periodic disturbance, which requires a material medium for its propagation. |
| |
|
Electromagnetic wave is a disturbance, which does not require any material medium for its propagation and can travel even through vacuum. |
| |
|
Longitudinal wave is a wave motion in which the particles of the medium oscillate about their mean positions in the direction of propagation of the wave. |
| |
|
Transverse wave is a wave motion in which the particles of the medium oscillate about their mean positions at right angles to the direction of propagation of the wave. |
| |
|
Pulse is a sudden and short disturbance. |
| |
|
Wavelength is the distance between the two nearest points on a wave. |
| |
|
Frequency is the number of waves produced per second. |
| |
|
Time period is the time taken by a wave to travel a distance equal to its wavelength. |
| |
|
Wave velocity is the distance
traveled by a wave in one second. |
