प्रश्न
An insect is sitting in front of a plane mirror at a distance of one meter from it.
- Where is the image of insect formed?
- What is the distance between insect and its image?
- State any two characteristics of image formed in a plane mirror.
उत्तर
(i) Distance of insect from plane mirror = u = 1 m
We know in the case of plane mirror, distance of object from plane mirror is equal to distance of image of the object from the plane mirror.
∴Distance of the image of insect from plane mirror = v = u – 1 m
(ii) Distance between insect and its image = u + v = 1 + 1 = 2 m
(iii) Characteristics of the image formed by a plane mirror :
(a) Image formed is virtual.
(b) Image formed is erect.
(c) Image formed is of same size as that of the object.
