Transverse and Longitudinal Waves in Physics

# data[].attributes.body
Sound Waves are waves made of compression and refraction and sound is then made through a medium of air. The motion of the waves are parallel and anti-parallel to the direction of the transport. The wavelength of a wave is the distance that the movement of a wave travels along the medium in one complete wave cycle.

Surface Waves are mainly known as Love waves or L waves and Rayleigh waves. A seismic wave is a wave that travels through Earth due to the cause of something like an earthquake or an explosion. Love Waves have a transverse motion which means there motion is perpendicular to the direction of travel just like light waves. Rayleigh Waves have both longitudinal which means the movement is parallel to the direction of travel and transverse motion.

Longitudinal Waves are waves in which the movement of the medium is the same direction as or the opposite direction to the direct direction the wave is traveling to. These waves are also called  compression waves and pressure waves because these waves produce a compression and rare refraction as they travel through their medium and they produce increases and decreases in pressure. Sound is an example of this wave.

Transverse Waves cause the medium that they travel through to vibrate at a right angle to the direction of the energy that is being carried by the medium. The movement of the medium is perpendicular to the direction of the propagation of the wave. Light and ripples in a pond are examples of transverse waves.

A mechanical wave is a wave that transfers energy through a medium. A mechanical wave requires a starting energy input and once it is put in it travels through the medium as the energy is transferred. These waves have a limited movement through their medium. The amplitude of a mechanical wave is measured in an unusual way, their movement is divided by a reduced wavelength. There are 3 types of mechanical waves : Transverse Waves, Longitudinal Waves, and Surface Waves.
