Ripple Tank:
Ripple Tank Is a device to produce water waves and to study their characteristics.
Explanation Of Ripple Tank:
The apparatus consist of a rectangular tray having glass bottom and is placed nearly half metre above the surface of a table . Waves can prodused on the surface of water present in the tray by means of a vibrator (paddle).
Wave:
The Disturbance In the medium Is Called Wave.
Types Of Wave:
1.Mechanical Waves:
Waves which require any medium for their propagation are called mechanical waves. e.g (water waves,sound waves)
2.Electromagnetic Waves:
Waves which do not require any medium for their propagation are called electromagnetic waves.
Simple Hormonic Motion:
Simple Hormonic Motion (SHM) is to and fro oscillatory motion in which acceleration of the body is directly proportional to the displacement of the body from the mean position and is always directed towards the mean position .
Features Of SHM:
i. A body excuting SHM always vibrates about fixed position .
ii. Its acceleration is always directed towards mean position .
iii. Its velocity is Maximum at the mean position and zero at extreme positions.
