Answer:

option (D)

Explanation:

your distance from the plane mirror = 2.4 m

According to the property of the plane mirror, the distance between the object and the mirror is equal to the distance between the image and the mirror.

So, the distance  between you and your image is two times the distance between you and mirror.

the distance between you and your image = 2 x 2.4 = 4.8 m

In order to take a picture of yourself in the mirror, you will have to dial in at a distance of  4.8 m.

A plane mirror is any reflecting surface. According to the principle of plane mirrors, the distance between the object and the mirror is found to be twice the distance between the image and the mirror.

As a result of this, in order to take a picture of yourself in the mirror, you will have to dial in at a distance of  4.8 m.
