Light at 633 nm from a helium-neon laser shines on pair of parallel slits separated by 1.45×10-5 m and an interference pattern is observed on a screen 2.00 m from the plane of the slits.
(a) What is the distance from the central maximum to the first bright fringe?
(b) What is the angle from the central maximum does the second dark fringe appear?
