Which among the following mirror(s) always forms virtual and erect image?
(A) Convex mirror
(B) Plane mirror
(C) Concave mirror

Correct option is C

Sol: The correct answer is (c) Both A and B

Convex mirror and Plane mirror always form virtual and erect images.

Key Points:

Convex Mirror:

• A convex mirror always forms a virtual, erect, and diminished image, regardless of the object's position.
• This is because the reflected rays diverge and appear to originate from a point behind the mirror.

Plane Mirror:

• A plane mirror always forms a virtual and erect image that is of the same size as the object.
• The image appears to be at the same distance behind the mirror as the object is in front of it.

​Concave Mirror:

• A concave mirror can form both real and inverted images as well as virtual and erect images, depending on the object's position:
  • Virtual and erect image: Only when the object is placed very close to the mirror (within the focal length).
  • Otherwise, it forms a real and inverted image.
