The field of view is maximum for

Options

A. plane mirror
B. concave mirror
C. convex mirror
D. None of these

Answer

To determine which type of mirror has the maximum field of view, we need to analyze the characteristics of three types of mirrors: convex, plane, and concave mirrors.

### Step-by-Step Solution

1. **Understanding Field of View**:
- The field of view is defined as the region between the extreme reflected rays from a mirror. This region determines what an observer can see when looking into the mirror.

2. **Analyzing Convex Mirrors**:
- Convex mirrors are curved outward. They reflect light rays that diverge, which means they spread out. The extreme reflected rays from a convex mirror create a wide angle, resulting in a larger field of view.
- This allows an observer to see a larger area behind them when looking into a convex mirror.

3. **Analyzing Plane Mirrors**:
- Plane mirrors have a flat surface. They reflect light rays at the same angle they hit the mirror. The field of view is limited to the angle of incidence and reflection, which is narrower compared to a convex mirror.
- Thus, while plane mirrors provide a clear image, their field of view is not as extensive as that of convex mirrors.

4. **Analyzing Concave Mirrors**:
- Concave mirrors are curved inward. They can focus light to a point and create a smaller field of view. The extreme reflected rays converge, which means the observer can only see a limited area in front of the mirror.
- Therefore, concave mirrors have the smallest field of view among the three types.

5. **Conclusion**:
- Based on the analysis, we can conclude that the convex mirror has the maximum field of view compared to plane and concave mirrors.

### Final Answer
- The field of view is maximum for a **convex mirror**.
