Question

What are waves and it's types

Answer 1

There are three categories: Longitudinal wave *s - Movement of the particles are parallel to the motion of the energy. Soundwaves moving through the air is an example of this type of wave. Transverse wave *s - movement of the particles are at right angles (perpendicular) to the motion of the energy.

Answer 2

Every sound we hear, every photon of light that hits our eyes, the movement of grass blown by the wind and the regular beat of the tides are all examples of waves. They are all around us.  Visible, physical wave*s such as those we see when a rock is thrown into water are what many people think about when they first began to think about waves. These waves have distinct properties specific to their type but also exhibit characteristics in common with more abstract waves such as sound waves and light (electromagnetic) waves

There are three categories:

Longitudinal wave*s - Movement of the particles are parallel to the motion of the energy.  Sound waves moving through the air is an example of this type of wave.Transverse wave*s - movement of the particles are at right angles (perpendicular) to the motion of the energy. Movement of a wave through a solid object like a stretched rope or a trampoline is an example of this type of wave.Surface wave*s - particles travel in a circular motion.  These waves occur at interfaces.  Examples include waves in the ocean and ripples in a cup of water.  One consequence of occurring at an interface is that the motion of the particles diminish with distance from the interface.  The further from the interface the smaller the rotation of the particles until as some distance from the surface, there is no more movement or energy propagation.
