Options

A. diverging lens
B. converging lens
C. cylindrical lens
D. none of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Definition**: A convex lens is a type of lens that is thicker in the middle than at the edges. It is designed to converge light rays that are coming in parallel to its principal axis.

2. **Identifying Alternative Names**: A convex lens is commonly referred to as a "converging lens." This name comes from its ability to bring parallel rays of light to a single point, known as the focus.

3. **Explaining the Function**: When a ray of light passes through a convex lens, it bends towards the principal axis and converges at a point. This is why it is called a converging lens; it converges or focuses light rays.

4. **Conclusion**: Therefore, a convex lens is also called a converging lens.

**Final Answer**: A convex lens is also called a converging lens.
