1.2. Power Calculation

Try these first

1. 1.

   What is wave power?

   Hint

   Consider energy in relation to wave motion.

2. 2.

   Define group velocity.

   Hint

   Think about the relationship between wave speed and energy transmission.

3. 3.

   What is the formula for wave power?

   • E × T
   • e × CG
   • E × h

   Hint

   Focus on the relationship between energy and wave speed.

4. 4.

   True or False: Mass transport in waves decreases with higher wave steepness.

   • True
   • False

   Hint

   Think about how wave energy relates to particle motion.

5. 5.

   A wave in deep water has a height of 2 meters and speed C0 = 16 m/s. Calculate the height of that wave if it enters shallow water where its speed is C = 10 m/s.

   Hint

   Substitute the values properly and calculate carefully.

6. 6.

   Consider a scenario with steep waves averaging 5 meters in height. Discuss the implications of their mass transport velocity compared to waves of a longer period with a height of 1 meter.

   Hint

   Reflect on the factors affecting wave steepness and energy.
