JEE Main 2016 — Wave Optics Question with Solution
From: JEE Main 2016 (Online) 9th April Morning Slot
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 , the value of d0 is close to :
