What to Focus On

  • Sound is produced by vibration.
  • Sound is a mechanical wave.
  • A medium is needed for sound to travel.
  • Mechanical waves need a medium.
  • Electromagnetic waves do not need a medium.
  • Mechanical waves can be transverse or longitudinal.
  • Human hearing range is 16 Hz to 20,000 Hz.
  • Below 16 Hz are infrasonic waves.
  • Above 20 kHz are ultrasonic waves.

Common Mistakes to Avoid

Sound can travel in vacuum if it is strong enough.

Transverse waves are the type of sound wave that travel in air and liquid.

Electromagnetic waves and sound waves behave the same way because both are waves.

Memory Tips

Sound is a result of vibration

Sound needs a medium to travel

Electromagnetic waves need no medium

Human audible range is 16 Hz to 20,000 Hz
