WAVESA wave is an oscillation accompanied by a

transfer of energy that travels through space or mass.

Wave motion transfers energy from one point to another.

WAVE MOTION

A wave motion is the propagation of disturbance from the point of a medium to other parts of it.

Transverse Wave

A transverse wave is a wave in which the particles of the medium vibrate perpendicular to the direction of propagation of the wave.

Examples of transverse waves

Light waves Radio waves Water wave UV rays X rays

Longitudinal waves

A longitudinal wave is a wave in which the particles of the medium vibrate in a direction parallel to the direction of propagation of the wave.

Examples of longitudinal waves Sound waves

Waves in slink

Vibration in gases

Oscillation in spring

Tsunami waves

Characteristics of transverse waves

Wave length It is the distance between any two consecutive points which are in the same state of vibration.Crust It is the elevated portion of the wave.Trough It is the depressed portion of the wave.Frequency It is the number of cycles per second

Velocity of a wave = frequency of the wave * wavelength of the wave
