In a Young's double slit experiment the slit separation is ( 0.5 ~m ) from the slits. For a monochromatic light of wavelength ( 500 ~nm ), the distance of ( 3^ r d ) maxima from ( 2^ nd ) minima on the other side is

Options

  1. A( 2.75 ~mm )
  2. B( 2.5 ~mm )
  3. C( 22.5 ~mm )
  4. DNone of above

Correct answer

D. None of above

Step-by-step solution

Distance between third maxima and second minima on the other side, ( aligned &x= 3 D d + (2 2-1) D 2 ~d = 9 D 2 ~d & x = 9 500 10⁻⁹ 0.5 2 0.5 10⁻³ =2250 10⁻⁶=2.25 ~mm aligned )
