Question

A concave lens is shown here. According to the model, a lens disperses rays after passing through it. Which item below most likely uses a concave lens to perform its typical function?

Answer 1

The item below that most likely uses a concave lens to perform its typical function is telescope.

A concave lens disperses rays after passing through it. This means that it makes parallel rays diverge and diverge rays even further. Concave lenses are used in a variety of applications, but the one that most likely uses a concave lens to perform its typical function is a telescope.

Telescopes use concave lenses to collect light from distant objects and focus it on a smaller area, making the objects appear larger and closer. Magnifying glasses use convex lenses to converge rays and make objects appear larger. Eyeglasses can use either convex or concave lenses, depending on the type of vision correction needed.
