Solution:
CONCEPT:
- Plane Mirror: A plane mirror is a mirror with a flat (planar) reflective surface.
The characteristics of an image formed in a plane mirror:
- The image formed by the plane mirror is virtual and erect i.e. image cannot be projected or focused on a screen.
- The distance of the image ‘behind’ the mirror is the same as the distance of the object in front of the mirror.
- The size of the image formed is the same as the size of the object.
- The image is laterally inverted, i.e. left hand appears to be right hand when seen from the plane mirror.
- If the object moves towards (or away from) the mirror at a certain rate, the image also moves towards (or away from) the mirror at the same rate.
EXPLANATION:
From the above discussion, we can say that,
- The image formed by Plane Mirror is always Virtual and Erect. So option 1 is correct.
- A convex lens and a concave mirror forms both real and virtual images.
- A concave lens and a convex mirror can form only virtual images.
