Question 1.
What is group celerity?
Show hintHide hint
Think about how a group behaves differently from an individual.
Question 2.
How does phase velocity differ from group velocity?
Show hintHide hint
Consider their definitions and how they relate to wave behavior.
3Question 3.
What is the relationship between group velocity and phase velocity in deep water?
- Group velocity is equal to phase velocity
- Group velocity is half of phase velocity
- Group velocity is twice the phase velocity
Show hintHide hint
Think about how energy disperses across waves.
4Question 4.
True or False: Group Celerity increases in shallow water.
- True
- False
Show hintHide hint
Consider the definition of group velocity.
Question 5.
A coastal engineer needs to build a structure that can withstand waves with a phase speed of 12 m/s in deep water. What is the required group celerity?
Show hintHide hint
Use the formula C_G = C / 2.
Question 6.
Discuss how the change from deep to shallow water impacts the wave energy transfer. Explain with respect to group celerity.
Show hintHide hint
Consider the implications this change has for coastal engineering.
