Which lens is also called diverging lens?  

The correct answer is Concave lens.

Concept:

• A lens is a transparent piece of glass connected by two spherical surfaces.
• A transparent material bound by two surfaces, of which one or both surfaces are spherical, forms a lens.
  • A convex lens is thicker in the middle and thinner at the edges.
  • A concave lens is thinner in the middle and thicker at the edges.

Explanation:

• A concave lens is thinner in the middle and thicker at the edges.
• It is also known as a diverging lens because it diverges light rays that pass through it.
• The shape of a concave lens curves inward, causing incoming parallel rays of light to spread out after passing through the lens.

Thus, Concave lens is also called diverging lens.

Additional InformationConvex lens

• A convex lens is thicker in the middle and thinner at the edges.
• It is also known as a converging lens because it converges light rays that pass through it.
• The shape of a convex lens bulges outward in the center and is thinner towards the edges.
