Question 1.
What ratio defines deep water conditions?
Show hintHide hint
Think of the relationship between depth and wavelength.
Question 2.
What is the formula for wave speed in shallow water?
Show hintHide hint
Focus on how depth affects speed.
3Question 3.
What defines deep water conditions?
- d/L > 0.5
- d/L < 0.05
- 0.05 < d/L < 0.5
Show hintHide hint
Consider the comparison of depth and wavelength.
4Question 4.
In shallow water, wave speed is dependent only on what factor?
- Wavelength
- Depth
- Frequency
Show hintHide hint
Reflect on the relationship between depth and wave speed.
Question 5.
Calculate the wave speed in shallow water at a depth of 4 meters. Use g = 9.81 m/s².
Show hintHide hint
Remember the relationship of wave speed to depth.
Question 6.
A wave has a wavelength of 50 meters in deep water. If the water depth is 30 meters, calculate if it’s deep water based on the d/L ratio. What is the wave speed?
Show hintHide hint
Determine if d/L ratio classifies it fully first.
