Questions and Answers

What determines the natural frequency of a body's vibrations?

  • The acceleration due to gravity and the length of the string
  • The surrounding medium
  • The force applied to the body
  • The shape and size of the body (correct)
  • Why do natural vibrations of a body only occur in vacuum?

  • To prevent resistance from the surrounding medium (correct)
  • To increase the frequency of vibration
  • To reduce the effect of gravity

  • Longitudinal waves (correct)
  • Surface waves
  • Transverse waves
