Question

If the magnification of the mirror is greater than 1, then the mirror is

• A. Concave mirror
• B. Convex mirror
• C. Plane mirror
• D. None

Answer 1

The Correct Option is A

To solve the problem, we need to identify which type of mirror can produce a magnification greater than 1.

1. Understanding Magnification:
Magnification (M) is the ratio of the height of the image to the height of the object. A magnification greater than 1 means the image is larger than the object.

2. Behavior of Different Mirrors:
- A plane mirror always forms an image of the same size, so its magnification is exactly 1.
- A convex mirror always forms diminished (smaller) images, so its magnification is always less than 1.
- A concave mirror can produce magnification greater than 1 when the object is placed between the pole and the focus, forming a virtual, erect, and enlarged image.

3. Conclusion:
Only a concave mirror can produce an image with magnification greater than 1.

Final Answer:
The mirror is a Concave mirror.
