Key Topics to Revise

1

Principle of Superposition

  • Two or more progressive waves travel simultaneously in a medium without affecting one another.
  • The resultant displacement of a particle is the vector sum of the individual displacements.
  • The principle holds for mechanical waves and electromagnetic waves.
2

Interference of Two Waves

  • Interference occurs when two coherent waves of the same frequency superpose.
  • The resultant intensity is not simply the sum of the individual intensities.
  • Constructive interference gives maximum intensity.
3

Conditions and Examples of Interference

  • The two waves must have a constant phase difference.
  • The waves should originate from the same source to remain coherent.
  • The amplitudes should be nearly equal, and for best interference exactly equal.
4

Quinck's Tube Experiment

  • Quinck's tube is used to demonstrate interference of sound waves.
  • It has two U-shaped tubes B and C, and two small tubes A and D at right angles.
  • Tube B can slide inside tube C.
