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.
