A wave is a kind of oscillation (disturbance) that travels through space and matter. Wave motions transfer energy from one place to another.

Waves play an important role in our daily life. This is because waves are a carrier of energy and information over large distances. Waves require some oscillating or vibrating source. Ocean surface waves were the first known waves. Later, other kinds were discovered.

Types of waves

  • In physics and technology, a wave (physics) carries energy that creates visible light, sound, and many other things

There are two categories of waves.

  • Mechanical waves
  • Electromagnetic waves

Mechanical waves

Waves which require any medium for their propagation are called mechanical waves.

For example:

Water waves, sound waves, and waves produced on the string and spring.

Electromagnetic waves

Waves which do not require any medium for their propagation are called electromagnetic waves.

For example:
