Example Problems

  • Wave compilation problem:

You're at the beach during a storm, and notice that the giant waves are rapidly hitting the coastline. After observation you notice that a waves are 6 m tall, and are hitting the shore every other second. You turn on the radio and hear that the wave speed is 30m/s. How far apart are the waves? 

If one wave can produce 35,000 hoursepower/mile of coastline in 10 seconds, what is the intensity of these waves? 

* HINTS: 746 Watts/Mechanical Horsepower, 2.6 km^2/Mile,

Lecture Material & Videos

Three types of waves: 

  1. Mechanical (i.e., crowd wave, sound) - requires a medium for wave to travel through
  2. Electromagnetic (i.e., radios, microwaves, light) - does not require a medium for wave to travel through
  3. Matter (i.e., electrons) - requires a medium for wave to travel through

Three modes of waves:

  1. Transverse (moves up and down)
  2. Longitudinal (moves left and right)
  3. Combination (moves left, right, up, and down, essentially in a circular motion)
