YDSE: Fringe Width & Fringe Positions

In a double slit experiment, the distance between slits is increased 10 times, whereas their distance from screen is halved, the fringe width

Show answer and solution

Answer: (c)

  1. β=λDd\beta = \frac{\lambda D}{d}
  2. β′=λ(D/2)10d=120β\beta' = \frac{\lambda (D/2)}{10d} = \frac{1}{20}\beta
  3. So the answer is (c).
