In Young's double slit experiment, the slit separation is made threefold by keeping remaining setup same, the fringe width becomes

Options

  1. A1 9 times
  2. B1 3 times
  3. C9 times
  4. D3 times

Correct answer

B. 1 3 times

Step-by-step solution

Fringe width , in terms of slit separation d and screen distance D is given by, = D d If d is made three times, fringe width becomes 1 3 times
