Even radio waves are most easily understood using an analogy with water waves. For earthquakes, there are several types of disturbances, which include the disturbance of Earth’s surface itself and the pressure disturbances under the surface. For sound waves, the disturbance is caused by a change in air pressure, an example of which is when the oscillating cone inside a speaker creates a disturbance. For water waves, the disturbance is in the surface of the water, an example of which is the disturbance created by a rock thrown into a pond or by a swimmer splashing the water surface repeatedly. However, light is not a mechanical wave it can travel through a vacuum such as the empty parts of outer space.Ī familiar wave that you can easily imagine is the water wave. The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling. Sound and water waves are mechanical waves meaning, they require a medium to travel through. Light, sound, and waves in the ocean are common examples of waves. Waves transfer energy from one place to another, but they do not necessarily transfer any mass.
