• Describe how to calculate each of wavelength,
  speed, and frequency if you know the other two
  factors. What is the wavelength of a 25 hertz
  wave traveling at 35 cm/s?

• Explain how a ship can use sound to map the ocean
  floor.

• Suppose that the sound waves of a sonar device on
  the ship are sent down and reflected back up by
  the sunken ship. If it takes 3 seconds for the
  waves to travel from their source to the sunken
  ship and back, what is the depth of the sunken
  ship?
