Question

The distance between the object and its image formed by a plane mirror appears to be $24cm$. What is the distance between the mirror and the object?

Answer 1

Step 1: Given data

The distance between the object and its image formed by a plane mirror = $24cm$

Step 2: Find the distance between the mirror and the object

The plane mirror forms the image at the same distance from the mirror as that of the object. We also know that the sum of the distance of the object and the image from the plane mirror is $24cm$. Thus,

Image distance$+$ Object distance $=24cm$

So, the object distance will be:

$=\frac{24}{2}=12cm$

Hence, the object distance is $12cm$.
