Question

Which mirror will always form the image of the same size as the object?

• A. Concave mirror
  
• B. Convex mirror
  
• C. Plane mirror
  
• D. All types of mirrors
  

Answer 1

The correct option is C Plane mirror


Plane mirrors always form an image of the same size as the object.
Convex mirrors can never form an image of the same size as the object, whereas concave mirrors can form only at one particular distance from them. At other positions, the image formed is either smaller or larger than the size of the object.
