Stationary wave

A stationary wave is a wave which doesn’t actually transfer energy.

That’s because it’s made up of two waves in opposite directions! The waves have:

  • the same frequency
  • the same amplitude
  • the same speed
  • the same wavelength

They interfere with each other, which produces some key features, which we’ll look at in the next sections.

Stationary waves are waves made up of two of the same waves in opposite directions interfering to proudce nodes and antinodes. They don’t transfer energy.
