Waves, sound and light


After this lesson, you should be able to:

  • Represent a longitudinal wave in a spring with a diagram
  • Describe the direction of motion of the particles of the medium relative to the direction of propagation of the wave
  • Distinguish between wavelength and amplitude of a longitudinal wave
  • Define period and frequency of a longitudinal wave
  • Define compression and rarefaction
  • Differentiate between transverse and longitudinal waves
  • Use the wave equation to solve problems on longitudinal waves
