3.3. Position of Nodes and Wave Group Velocity

Try these first

1. 1.

   What is the term used to describe points in a wave with no displacement?

   Hint

   Think of a wave where energy is not transfe

2. 2.

   What does Bernoulli's equation relate?

   Hint

   Remember it as fluid mechanics with three key aspects.

3. 3.

   What does Kp represent?

   • A coefficient of pressure
   • Wave amplitude factor
   • Pressure response factor

   Hint

   Think about how pressures change with water surface variations.

4. 4.

   True or False: Group velocity is always greater than phase velocity.

   • True
   • False

   Hint

   Recall how these two velocities are related.

5. 5.

   Explain how the understanding of wave mechanics can influence the design of coastal defenses.

   Hint

   Think about the specific ways waves interact with coastal structures.

6. 6.

   Given a wave with a wavelength of 10 meters and frequency of 1 Hz, calculate both phase and group velocity.

   Hint

   Use the relationship between wavelength, frequency, and velocity.
