Q1: What is a magnifying glass, and how is it structured?A1: A magnifying glass is a simple optical device consisting of a convex lens (typically plano-convex) mounted in a frame with a handle. The convex lens converges light rays, creating a magnified virtual image of an object placed within its ... Read More

Q1: What is a plano-convex lens, and how is it structured?A1: A plano-convex lens is an optical lens with one flat (plano) surface and one outward-curving (convex) surface. The convex side has a positive focal length, enabling it to focus light rays or collimate diverging beams. Its asymmetric ... Read More
