Answer 1

Answer:

Lens: A transparent material bound by two surfaces, of which one or both surfaces are spherical, forms a lens.

Lens: A transparent material bound by two surfaces, of which one or both surfaces are spherical, forms a lens.Convex lens: Convex lens is a transparent curved device that is used to refract light. A lens is usually made from glass. There are two different shapes for lenses. They are called convex and concave lens. A convex lens is thicker in the middle and thinner at the edges, it is also called a converging lens. A convex lens will focus light and make a real and inverted image. The size of the image will depend on the position of the object and lens.
