WAVE MOTION

A wave is a disturbance that carries energy from place to place.

TYPES OF WAVES

If the particle in the medium vibrates perpendicular to the direction of propagation of the wave then it is called TRANSVERSE WAVE

The crest is the highest point on

a wave.

PARTS OF A TRANSVERSE WAVE.

The trough is the lowest

point..



The wavelength is the horizontal distance, either between the

crests or troughs of two consecutive waves.

.

The amplitude is the peak value of a wave. The distance from the undisturbed level to

the trough or crest.


If the particle in the medium vibrates parallel to the direction propagation of the wave then it is called LONGITUDINAL WAVE

LONGITUDINAL WAVES

PARTS OF A LONGITUDINAL WAVE

The compression is the part of the longitudinal wave where the particles are crowded together.


The rarefaction is the part of the longitudinal wave where the particles

are spread apart.

The wavelength is the distance from compression to compression or rarefaction to rarefaction in a

longitudinal wave.
