In an experiment to demonstrate interference of flight using Young's slits, separation of two slits is doubled. In order to maintain same spacing of fringes, distance D of screen from slits must be changed to |
$D$ $\frac{D}{2}$ $2D$ $\frac{3D}{4}$ |
$2D$ |
$β=\frac{λD}{d}=\frac{λ(2d)}{2d}=β$ i.e., D' = 2D. |
