Question

In Young’s double slit experiment, the distance between slits and the screen is 1.0 m and monochromatic light of 600 nm is being used. A person standing near the slits is looking at the fringe pattern. When the separation between the slits is varied, the interference pattern disappears for a particular distance d₀ between the slits. If the angular resolution of the eye is $({{{1}} \over {60}})^o$, the value of d₀ is close to :

1 mm

2 mm

4 mm

3 mm
