Question 1.
What is the main governing equation used in wave mechanics?
Show hintHide hint
Think about equations that involve potential fields.
Question 2.
Define wave celerity.
Show hintHide hint
Consider how we relate speed to distance and time.
3Question 3.
What does the Laplace equation govern?
- Fluid flow
- Mass conservation
- Energy potential
Show hintHide hint
Think about how fluids move in potential fields.
4Question 4.
True or False: The dispersion relationship does not consider wave depth.
- True
- False
Show hintHide hint
Remember that depth plays a critical role in wave behavior.
Question 5.
If you have a wave with a wavelength of 5m and a period of 2s traveling in 8m of water depth, how would you use the dispersion relationship to check if this is a feasible situation?
Show hintHide hint
Ensure both sides of the equation balance to confirm feasibility.
Question 6.
You are given a water depth of 4m. What L would correlate with a period of 1.5s using the dispersion relationship?
Show hintHide hint
Trial and error may be required for L since it appears on both sides.
