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

The distance between the mirror and the object is equal to the distance between the mirror and the image formed in the case of a plane mirror. Here, the distance between the object and its image formed by a plane mirror is 24 cm. Hence, the distance between the mirror and the object would be half of it which would be 12cm.
