Question 1.
Define wave speed in your own words.
Show hintHide hint
Think about how fast you see ripples move on the water.
Question 2.
What does the Froude number measure?
Show hintHide hint
Recall how it helps classify flow types.
3Question 3.
What is the primary equation for wave speed under small amplitude conditions?
- a) c = g/y
- b) c = sqrt(gy)
- c) c = y/g
Show hintHide hint
Look for the equation derived in class.
4Question 4.
True or False: The Froude number helps classify flow as supercritical or subcritical.
- True
- False
Show hintHide hint
Remember the definitions we discussed.
Question 5.
How would you model the effects of wave height on what happens in a channel with a 5m depth if the wave travels at 4 m/s?
Show hintHide hint
Think about changing heights and apply both wave equations.
Question 6.
Design a small experiment using a ripple tank to illustrate the relationship between wave speed and depth. What variables would you measure?
Show hintHide hint
Control for amplitude to isolate the effect of depth.
