Why in Newton’s rings setup, the beam splitter (mirror) is kept at 450? (a) It allows light rays to incident at 450over the top surface of Plano convex lens
(b) It allows light rays to incident uniformly over the top surface of Plano convex lens
(c) It allows light rays to incident parallel over the top surface of Plano convex lens
(d) It allows light rays to incident at 900over the top surface of Plano convex lens
(b) It allows light rays to incident uniformly over the top surface of Plano convex lens
(c) It allows light rays to incident parallel over the top surface of Plano convex lens
(d) It allows light rays to incident at 900over the top surface of Plano convex lens
