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 mirro
r.
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.
