Question

if an object is placed at a distance of 1m in front of a plane mirror the distance between the object and image formed by a mirror will be
​

Answer 1

Answer:

the distance will be 2 meteres

Answer 2

Given: object placed at a distance of 1m in front of plane mirror

To find: distance between object and image formed by mirror

Explanation:

As we know that,

The image formed by the mirror is at same distance behind the mirror as object is in front of it.

distance of object from the mirror,$d_{o}$ = 1m

distance of image from the mirror,$d_{i}$ = 1m

So, total distance between object and image,d = $d_{o}$ + $d_{i}$

                                                                            d =(1+1)m

                                                                            d = 2m

Therefore, the distance between the object and image formed by a mirror will be 2m.
