In Young's double slit experiment the separation between the slits is doubled without changing other setting of the experiment to obtain same fringe width, the distance ' $D$ ' of the screen from slit should be made

Options:

Answer:

Solution:

Fringe width, $W = \frac{λ D}{d}$ Given: $d = 2 d$ $\Rightarrow W^{'} = \frac{λ D ^{'}}{2 d}$ Since given, $∴ ∴ W = W^{'} \frac{λ D}{d} = \frac{λ D ^{'}}{2 d} D^{'} = 2 D$
