Question

A parallel beam of light left parenthesis lambda equals 5000 text Å end text right parenthesis is incident at an angle alpha equals 30 to the power of ring operator end exponent with the normal to the slit plane in a young’s double slit experiment. Assume that the intensity due to each slit at any point on the screen is I subscript 0 end subscript. Point O is equidistant from S subscript 1 end subscript & S subscript 2 end subscript. The distance between slits is 1mm.

  1. the intensity at O is 4 I subscript 0 end subscript    
  2. the intensity at O is zero    
  3. the intensity at a point on the screen 4m from O is 4 I subscript 0 end subscript    
  4. the intensity at a point on the screen 4m from O is zero    

The correct answer is: the intensity at O is 4 I subscript 0 end subscript

In the figure shown, a parallel beam of light is incident on the plane of the slits of Young's double slit experiment. Light incident on the slit, S subscript 1 end subscript passes through a medium of variable refractive index mu equals 1 plus a x (where 'X' is the distance from the plane of slits as shown), up to a distance 'lambda' before falling on S subscript 1 end subscript . Rest of the space is filled with air. If at 'O' a minima is formed, then the minimum value of the positive constant a (in terms of l and wavelength 'lambda' in air) is:
