Refraction of Waves Flashcards
1
Q
If the substance or medium that a wave is travelling thorough changes…
A
the wave may change speed
2
Q
If the change is speed causes a change in direction…
A
we say the wave has refracted
3
Q
What does refracted mean?
A
If the change in speed causes a change in direction.
4
Q
The speed of the Wave is…Deep water
A
Fast
5
Q
The speed of the Wave is…Shallow water
A
Slow
6
Q
Explain the wave going from Deep to Shallow
A
- Water slows down on entering shallow water and refracts (towards normal)
- Wavelength decreases but their frequency is constant
7
Q
Explain the wave going from Shallow to Deep
A
- The waves speed up on entering deep water and refract (away from normal)
- Wavelength increases but the frequency is constant
