Question

The image formed by a mirror is virtual, erect and longer than the object, then the mirror will be

• A. convex mirror
• B. concave mirror
• C. plane mirror
• D. both convex and concave mirrors

Hint:

Remember: A concave mirror forms a magnified, virtual, and erect image when the object is within the focal point.

Answer 1

The Correct Option is B

Step 1: Understanding the image formation
A concave mirror can form a virtual, erect, and magnified image when the object is placed between the focus and the mirror. In such a case, the image appears larger (longer) than the object and is virtual and erect.

Step 2: Behavior of other mirrors
- A convex mirror always forms a diminished, virtual, and erect image, so it cannot satisfy the conditions of the problem.
- A plane mirror forms a virtual and erect image of the same size as the object.

Step 3: Conclusion
The only mirror that satisfies the conditions of forming a virtual, erect, and magnified image is the concave mirror.
\[ \boxed{\text{concave mirror}} \]
