1.5 Short Notes: Refraction of Waves

Refraction of Wave

Drawing Refracted Waves

  • When water wave travel from deep area to shallow area, it will refracted towards normal line.
  • Water wave will refract away from the normal line when travelling from shallow area to deep area.

Example question on refraction of waves


In Figure 1.20, a basin containing water is tilted. A drop of water is released into the basin. Draw the pattern of wave fronts in the basin.

Answer:

Wave formation that travel to the left is slower while the one heading to the right is faster.

Questions

  • How waves can be refracted?
  • Why frequency of a wave does not change when being refracted?
  • Sketch the pattern of wave fronts when the wave propagates through a shallow area and parallel to the normal line.

Answers

  • When there is a change in speed when passing a through a medium to another medium.
  • The wave is coming from same source.
