Question

Why is a convex lens used in telescopes?​

Answer 1

Refracting telescopes use lenses to bend the light to a specific focal point such that the object will be magnified to the viewer. This lens is a convex lens that bends the incoming light rays to a focal point within the telescope. The second lens is called the eyepiece.
