The central fringe in the interference pattern obtained in Young's double slit experiment will be a dark fringe when the phase difference between the waves from the two slits is

Options

  1. Azero
  2. B( 2 )
  3. C( )
  4. D( 3 )

Correct answer

C. ( )

Step-by-step solution

When the central fringe in the interference pattern in YDSE be a dark fringe, then path difference, will be ( 2 ). i.e., ( x= 2 ) ( ) Phase difference, ( aligned & = 2 x & = 2 2 = aligned )
