Question

How does a concave lens differ from a convex lens? A) A convex lens is another way to describe a plane mirror; a concave lens is curved. B) A concave lens us curved inward on both sides; a convex lens is curved on only one side. C) A convex lens has a thick center and thin edges; a concave lens has a thin center and thicker edges. D) A convex lens has a thin center and thick edges; a concave lens has a thick center and thiner edges.

Answer 1

Answer;

C) A convex lens has a thick center and thin edges; a concave lens has a thin center and thicker edges.

Explanation;

• Convex lens refers to the lens which merges the light rays at a particular point, that travels through it, while a concave lens can be identified as the lens which disperses the light rays around, that hits the lenses.
• A convex lens is thicker at the center, as compared to its edges, while a concave lens is thinner at the center as compared to its edges.
• A concave lens is thicker at the edges than in the middle and spreads light rays apart producing an image smaller than the actual object. A convex lens on the other hand, is thinner at the edges and thicker towards the center, that is they are bent towards a central point.

Answer 2

c. A convex lens has a thick center and thin edges; a concave lens has a thin center and thicker edges.
