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.
•
