Q. Lens which is thin at center and thick at edges is (December 2022, UGC NET)

1. Convex lens

2. Biconvex lens

3. Both (1) and (2)

4. Concave lense

Correct Ans: (4)

Explanation: A concave lens is characterized by its thin center and thick edges. This type of lens diverges light rays that pass through it, causing them to spread out. Concave lenses are used in applications such as correcting myopia (nearsightedness) in eyeglasses, in optical instruments, and for various scientific and industrial purposes. Their ability to spread light makes them essential in technologies like cameras and telescopes.
