A wave is a way of transferring energy from one place to another without transferring matter. Light, sound, x-rays, radio waves and water waves are all examples of waves.

In this topic you need to know about the following: -

  • The differences between transverse and longitudinal waves.
  • What wavelength, wavespeed, frequency and amplitude are.
  • What reflection and refraction are and how to measure it experimentally.
  • How to use the wave equation.

    • Use the arrows below to continue to revise.
