Two identical light waves, propagating in the same direction, have a phase difference . After they superpose the intensity of the resulting wave will be proportional to

Options

  1. A( / 2)
  2. B²( / 2)
  3. C²

Correct answer

C. ²

Step-by-step solution

Phase difference between the two identical waves = For identical wave, a₁=a₂=a After superposition, intensity of resultant wave aligned I & ( Amplitude) ² . & A² & (a₁²+a₂²+2 a₁ a₂ ) & (a²+a²+2 a² ) & 2 a²(1+ ) & 2 a² (2 ² 2 ) & 4 a² ² ( 2 ) & ² ( 2 ) aligned
