1.2. Expression of Particle Displacement

Try these first

1. 1.

   What is particle displacement?

   Hint

   Recall the original position of the water particle.

2. 2.

   What do D and B represent in the equations?

   Hint

   Think about the shape of the orbit.

3. 3.

   What type of motion do water particles exhibit in shallow water?

   • Elliptical
   • Circular
   • Linear

   Hint

   Think about the shape of the orbit in shallow waters.

4. 4.

   True or False: In deep water, the motion of water particles is elliptical.

   • True
   • False

   Hint

   Recall the distinctions made in class regarding depth.

5. 5.

   Determine the type of particle motion for a wave with a height of 1.5m and depth of 10m.

   Hint

   Consider the proportionality between depth and wave properties.

6. 6.

   If a water particle at a certain depth follows an orbit of 0.8m radius in deep water, how does this affect the equations for D and B?

   Hint

   Revisit the deep water equations to understand the circular relationship.
