Question 1.
What characteristic does small amplitude wave theory assume about wave height relative to depth?
Show hintHide hint
Think about relationships between height and depth in water.
Question 2.
State the wave speed equation derived in this section.
Show hintHide hint
This equation includes gravity and water depth parameters.
3Question 3.
What is the formula for wave speed in small amplitude waves?
- c = gy
- c = √(gy)
- c = g/y

Question 5.
A wave travels at a speed of 6 m/s in a channel. If the gravitational acceleration is 9.81 m/s², calculate the depth of the water.
Show hintHide hint
Use the wave speed formula provided.
Question 6.
If a certain channel has a depth of 4 meters and the speed of small amplitude waves is calculated as 7 m/s, find the value of gravitational acceleration assumed during this calculation.
Show hintHide hint
Think about how to isolate the gravitational acceleration from the formula.
