1. Water Particle Displacement

Try these first

1. 1.

   What shape do water particles trace in shallow water?

   Hint

   Think about the relationship of the axes.

2. 2.

   What is the semi-major axis in a wave motion?

   Hint

   Connect it with the axis of an ellipse.

3. 3.

   What type of orbit do water particles trace in deep water?

   • Elliptical
   • Circular
   • Straight

   Hint

   Think about the characteristics of deep-water waves.

4. 4.

   True or False: Water particle displacement can be approximated as elliptical in deep water.

   • True
   • False

   Hint

   Compare the conditions of shallow and deep waters.

5. 5.

   If the wave height is 2 meters and the wavelength is 20 meters, calculate the horizontal and vertical displacements of water particles at a given instance where k = 0.314.

   Hint

   Start by substituting the wave height into the equations provided.

6. 6.

   Explain the effects of different wave heights on the elliptical orbits of water particles in shallow water.

   Hint

   Consider how wave energy influences particle movement.
