What is the other name of a diverging lens ?

Options

A. Concave lens
B. Convex lens
C. Plane lens
D. Both B and C

Answer

**Step-by-Step Solution:**

1. **Understanding Diverging Lens**: A diverging lens is a type of lens that causes light rays to spread apart or diverge after passing through it. This lens is thinner at the center and thicker at the edges.

2. **Characteristics of Diverging Lens**: When parallel light rays enter a diverging lens, they refract outward, creating the effect of diverging. This is opposite to a converging lens, which brings light rays together.

3. **Identifying the Other Name**: The other name for a diverging lens is a "concave lens." This term is derived from the shape of the lens, which is curved inward, resembling a cave.

4. **Conclusion**: Therefore, the answer to the question "What is the other name of a diverging lens?" is "concave lens."

**Final Answer**: The other name of a diverging lens is a concave lens.
