What to Focus On

  • Sound is produced by vibrations and travels as waves
  • Waves transfer energy, not matter
  • Wave speed equals frequency times wavelength (v = f × λ)

  • Sound requires a medium to travel - cannot travel through vacuum
  • Sound travels as longitudinal waves in fluids
  • Speed of sound is highest in solids, lowest in gases

  • Mechanical waves need a medium; electromagnetic waves do not
  • Sound is a mechanical, longitudinal wave
  • Light is an electromagnetic, transverse wave

Common Mistakes to Avoid

Sound waves and electromagnetic waves are the same thing and both need a medium to travel

Higher frequency always means louder sound

SONAR and RADAR work on the same principle and can be used interchangeably

Memory Tips

Sound requires a medium to travel

Wavelength, frequency, and amplitude parameters

Speed = Frequency × Wavelength formula

Audible range 16 Hz to 20,000 Hz
