how does the incident wavelength compare with the reflected? Why?

Mar 18th, 2015

  • the wave speed is always greatest in the least dense medium,
  • the wavelength is always greatest in the least dense medium,
  • the frequency of a wave is not altered by crossing a boundary,
  • the reflected pulse becomes inverted when a wave in a less dense medium is heading towards a boundary with a more dense medium,
  • the amplitude of the incident pulse is always greater than the amplitude of the reflected pulse.
