In a Young's double slit experiment with light of wavelength , fringe pattern on the screen has fringe width . When two thin transparent glass (refractive index ) plates of thickness t₁ and t₂ (t₁>t₂ ) are placed in the path of the two beams respectively, the fringe pattern will shift by a distance

Options

  1. A( -1 ( t₁ t₂ )
  2. Bt₁ t₂
  3. C( -1 (t₁-t₂ .
  4. D( -1 ) (t₁+t₂ )

Correct answer

C. ( -1 (t₁-t₂ .

Step-by-step solution

aligned Shift & = ( -1) t₁- ( -1) t₂ & = ( -1) (t₁-t₂ ) aligned
