A wave is a way in which energy travels from one place to another. There are many kinds of waves, such as water waves, sound waves, light waves, radio waves, microwaves and earthquake waves. All waves have some things in common.
In physics, a wave is an oscillation accompanied by a transfer of energy that travels through a medium (mass). Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission mediumâthat is, with little or no associated mass transport.
