TO DETERMINE FOCAL LENGTH OF CONVEX LENS

MATERIAL REQUIRED Convex Lens, Optical Bench THEORY A lens is a piece of transparent material which concentrates or disperses light rays when passes through them by refraction. According to the shape and purpose of the lens, they are classified into two types convex lens and concave lens. A lens that is thicker at its center
