What is a concave lens and a convex lens

1.	What is a concave lens and a convex lens
Answer» A convex lens or converging lens focuses the light RAYS to a specific point whereas a concave lens or diverging lens diverges the light rays. ... Concave lenses and convex lenses are often used TOGETHER with known as Concave – Convex lens. When these lenses are combined they PRODUCE sharper IMAGES.
