Two parallel slits

0.6\,mm

apart are illuminated by light source of wave length

6000\,\mathop \mathrm{A}\limits^ \circ

. The distance between two consecutive dark fringes on a screen

1\,\,m

away from the slits is

View answer and explanation

Correct option: A

1\,mm

Option A (1 mm) is correct because it uses the formula for fringe width in Young's double-slit experiment to calculate the distance between consecutive dark fringes.
