how many kinds of mechanical waves are there
Answers
There are three types of mechanical waves. They are longitudinal waves, transverse waves, and surface waves.
Explanation:
There are three types of mechanical waves:
transverse waves, longitudinal waves, and surface waves.electro magnetic waves are different from mechanical waves.
Transverse wave:
It is the form of wave in which particles of medium vibrates about their mean position perpendicular to the direction of motion of wave.
To see an example, move an end of a Slinky (whose other end is fixed) to the left-and-right of the Slinky, as opposed to to-and-fro. Light also has properties of a transverse wave, although it is an electromagnetic wave.
Longitudinal wave:
Longitudinal waves cause the medium to vibrate parallel to the direction of the wave. It consists of multiple compressions and rarefactions. The rarefaction is the farthest distance apart in the longitudinal wave and the compression is the closest distance together. The speed of the longitudinal wave is increased in higher index of refraction, due to the closer proximity of the atoms in the medium that is being compressed. Sound is a longitudinal wave.
Surface waves:
This type of wave travels along the surface or interface between two media. An example of a surface wave would be waves in a pool, or in an ocean, lake, or any other type of water body. There are two types of surface waves, namely Rayleigh waves and Love waves.
