• Marine mammals use sound to obtain information
  about their surroundings and to find food. They
  do this by producing sounds or sonar clicks that
  are reflected back when they strike an object.

• Justin is riding in his car while banging his
  favorite hip-hop song. When he passes by his
  neighbors house, the walls begin to vibrate. The
  vibrating of the walls is due to ________.
• Interference
• Resonance
• Frequency

• Observe the diagram on the right of the sound
  wave produced by a radio as the volume is
  increased. What inference can be made about how
  sound waves change as volume increases?
• The sound wave gains more energy and the
  amplitude of the wave increases.
• The sound wave loses energy and the amplitude of
  the wave decreases.
• The sound wave gains more frequency and the
  wavelength decreases.
• The sound wave loses frequency and the wavelength
  increases.
