Which of the following is (are) converging mirror (s)?

Options

A. Convex mirror
B. Concave mirror
C. Plane mirror
D. Both (a) and (b)

Answer

To determine which of the following mirrors is a converging mirror, we need to analyze the types of mirrors and their properties:

### Step-by-Step Solution:

1. **Understand the Types of Mirrors**:
- There are three main types of mirrors: concave, convex, and plane mirrors. Each has distinct characteristics in how they reflect light.

2. **Identify the Characteristics of a Convex Mirror**:
- A convex mirror bulges outward. When parallel rays of light strike a convex mirror, they reflect outward and diverge. Therefore, a convex mirror cannot be a converging mirror.

3. **Identify the Characteristics of a Concave Mirror**:
- A concave mirror curves inward. When parallel rays of light hit a concave mirror, they reflect and converge towards a focal point. This makes the concave mirror a converging mirror.

4. **Identify the Characteristics of a Plane Mirror**:
- A plane mirror has a flat reflecting surface. Light rays that strike a plane mirror reflect at the same angle they arrive, without converging or diverging. Thus, a plane mirror is neither a converging nor a diverging mirror.

5. **Conclusion**:
- From the analysis, the only mirror that acts as a converging mirror is the concave mirror. Convex and plane mirrors do not converge light rays.

### Final Answer:
The converging mirror is the **concave mirror**.
