Q 01: What is superposition?
  • (A) The combination of two or more waves to form a single wave
  • (B) The cancellation of two waves resulting in no wave
  • (C) The reflection of waves from a surface
  • (D) The absorption of waves by a medium

Q 02: Interference occurs when:
  • (A) Two waves of the same frequency overlap
  • (B) Two waves of different frequencies overlap
  • (C) A wave reflects off a surface
  • (D) A wave passes through a medium

Q 03: Constructive interference occurs when:
  • (A) Two waves cancel each other out
  • (B) Two waves reinforce each other
  • (C) Waves reflect off a surface
  • (D) Waves pass through a medium

Q 04: Destructive interference occurs when:
  • (A) Two waves cancel each other out
  • (B) Two waves reinforce each other
  • (C) Waves reflect off a surface
  • (D) Waves pass through a medium

Q 05: The phenomenon of interference is a result of:
  • (A) The superposition of waves
  • (B) The absorption of waves by a medium
  • (C) The reflection of waves from a surface
  • (D) The dispersion of waves

Q 06: In the case of completely destructive interference:
  • (A) The resulting wave has twice the amplitude of the individual waves
  • (B) The resulting wave has half the amplitude of the individual waves

  • (B) The reflection of sound waves
  • (C) The bending of light waves around an obstacle
  • (D) The absorption of heat waves by a surface

Q 08: The principle of superposition states that when two or more waves meet at a point in space:
  • (A) They cancel each other out completely
  • (B) They undergo reflection
  • (C) They combine to form a single wave
  • (D) They scatter in different directions

Q 09: Coherent sources of waves are sources that:
  • (A) Have the same amplitude but different frequencies
  • (B) Have different amplitudes but the same frequency
  • (C) Have the same amplitude and frequency and a fixed phase relationship
  • (D) Have different amplitudes and frequencies and no phase relationship

Q 10: The interference pattern produced by two coherent sources depends on:
  • (A) The amplitude of the sources
  • (B) The frequency of the sources
  • (C) The wavelength of the sources
  • (D) All of the above
