MCQ
In Young's double slit experiment, the phase difference between the light waves reaching third bright fringe from the central fringe will be ($\lambda$ $=6000 Å$ )
  • A
    Zero
  • B
    $2\pi $
  • C
    $4\pi $
  • $6\pi $

Answer

Correct option: D.
$6\pi $
d
(d)$\because n = 3,\;\;\therefore 2n\pi  = 2 \times 3\pi  = 6\pi $
