Answer

2 main types (transverse and longitudinal)

Step 1: Definition of a wave

A wave is a propagating disturbance that transfers energy from one place to another without the transfer of matter.

Step 2: Types of waves

Waves are classified based on the direction of oscillation (displacement of particles) relative to the direction of wave propagation into two main types:

  • Transverse waves: The particles of the medium oscillate perpendicular to the direction of wave propagation (e.g., waves on a string, light waves).

  • Longitudinal waves: The particles of the medium oscillate parallel to the direction of wave propagation (e.g., sound waves).

Waves are also classified by the need for a medium:

  • Mechanical waves: Require a material medium (e.g., sound, water waves). These can be transverse or longitudinal.

  • Electromagnetic waves: Do not require a medium and propagate through vacuum (e.g., light, radio waves). These are transverse.
