What to Focus On

  • Sound is a form of energy that produces hearing.
  • A vibrating body produces sound.
  • Sound cannot travel in vacuum.

  • Sound in air travels as a longitudinal wave.
  • Compressions are regions of high pressure.
  • Rarefactions are regions of low pressure.

  • Amplitude measures maximum displacement from mean position.
  • Time period is the time for one vibration.
  • Frequency is vibrations per second.

Common Mistakes to Avoid

Sound can travel in vacuum if the source is loud enough.

Sound travels fastest in air and slowest in solids.

A wave means the particles of air move from the source to the listener.
