Question

1 Describe the shape of a) a concave lens. b) a convex lens.​

Answer 1

Answer:

a) The shape of a concave lense is round inward that bends the beams outward, causing divergence of the rays of light falling on it, so it is known as a diverging lens. 

b) convex lens is also known as a converging lens. A converging lens is a lens that converges rays of light that are traveling parallel to its principal axis. They can be identified by their shape which is relatively thick across the middle and thin at the upper and lower edges.
