Question 1.
Define wave speed.
Show hintHide hint
Consider how waves move through a medium.
Question 2.
What defines shallow water?
Show hintHide hint
Think about the depth-to-wavelength ratio.
3Question 3.
What is the wave speed formula for shallow waters?
- c_naught = √(gL/2π)
- c = √(gd)
- c = gL
Show hintHide hint
Recall the surface wave conditions.
4Question 4.
True or False: In deep water, wave speed depends on the water depth.
- True
- False
Show hintHide hint
Think about the definitions of water classifications.
Question 5.
A wave travels with a length of 40 meters in deep water. If it is observed to travel at a speed of 3.14 m/s, what is the depth of the water? Use the formula c_naught = √(gL/2π).
Show hintHide hint
Use wave speed and rearrangement carefully.
Question 6.
If you are at a coastal area where the water depth is 3 meters, what is the wave speed using c = √(gd)? Calculate the wave characteristics if the gravitational acceleration is given as 9.81 m/s².
