Four independent waves are represented by equations (1) X ₁= a ₁ t (3) X ₂= a ₂ 2 t (2) X ₃= a ₁ ₁ t (4) X ₄= a ₁ ( t + ) Interference is possible between waves represented by equations

Options

  1. A3 and 4
  2. B1 and 2
  3. C2 and 3
  4. D1 and 4

Correct answer

D. 1 and 4

Step-by-step solution

Coherent sources should have same frequency and wavelength and constant or zero phase difference. Frequency is same only for wave X₁ and X₄ and phase difference =
