Question

If an object is placed at a distance of 0.7 m in front of a plane mirror, the distance between the object and the image formed by the mirror will be *

Answer 1

Answer:

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

If distance of object from mirror = 0.5 m

Then distance of image from mirror = 0.5 m

So, distance between object and mirror = 0.5 m+ 0.5m = 1m

Answer 2

Given:

Distance from the mirror - 0.7m

To find:

The distance between the object and the image that is formed on the mirror.

Solution:

Distance from the mirror - 0.7m

When an object is placed at a certain distance from the mirror, the image formed will also be at the same distance.

Here, the distance from the mirror is 0.7 m

so the distance of the image formed at the mirror will also be 0.7m

The total distance between the object and the image formed will be

$= 0.7m + 0.7m$

$= 1.4m$

Therefore, the total distance between the object and the image formed will be 1.4m
