Interference

Cards (5)

  • The principle of superposition states that if waves from two sources meet, they interfere and the resultant displacement is the vector sum of their displacements
  • Interference occurs when two waves travelling in the same region superpose
  • Path difference is the difference in distance travelled by two waves
  • Phase difference is the difference in position of two points on a wave in the same oscillation cycle
  • Constant phase difference means both particles have the same frequency
