Question

Which among the following is NOT a characteristic of the image of an object formed by a plane mirror? 
1. Erect
2. Laterally inverted 
3. Real 
4. Virtual 

Answer 1

Correct Answer - Option 3 : Real 

The correct answer is Real.

• Reflection From Plane Mirror
  • A plane mirror always forms a virtual and laterally inverted image.
  • The size of the image is equal to that of the object.
  • The distance of the image from the mirror is equal to the distance of the object from the mirror.
  • If an object moves towards (or away from) a plane mirror with speed u, relative to the object, the image moves towards (or away) with a speed of 2u.
  • If a plane mirror is rotated by an angle θ, keeping the incident ray fixed, the reflected ray is rotated by an angle of 2θ.
  • To see his full image in a plane mirror, a person requires a mirror of at least half of his height.
