How does a concave magnifying glass differ from a convex one in terms of its optical properties and practical applications?

Answer 1

A concave magnifying glass is thinner in the middle and thicker at the edges, causing light rays to diverge. This results in a virtual and diminished image. A convex magnifying glass is thicker in the middle and thinner at the edges, causing light rays to converge. This produces a virtual and magnified image. In terms of practical applications, a concave magnifying glass is used in devices like cameras and projectors to create a smaller image, while a convex magnifying glass is commonly used in magnifying glasses and reading glasses to enlarge text for easier viewing.
