29.Parallel rays are incident on a thick plano-convex lens having radius of curvature R, refractive index u and thickness t. When rays are incident on plane surface they converge at a distance x from plane surface when ray are incident on curved surface Then rays converges at y distance from curved surface then (a) x = y (b) x > y (c) x < y (d) none |
