Properties of waves

Waves exhibit various properties which can be conveniently demonstrated using the ripple tank.

It consists of a transparent tray filled with water and a white screen as the bottom. On top we have a source of light.

A small electric motor (vibrator) is connected to cause the disturbance which produces waves.

The wave fronts represent wave patterns as they move along.

What is a wave?. A wave is simply a disturbance that moves through a medium . Other waves do not require a medium to travel i.e. they can travel in a vacuum, are known as electromagnetic waves e.g. radio, X-rays, gamma rays UV rays etc. Other waves require a material medium to be transferred and are called mechanical waves i.e. water, sound waves etc.
