Question

Two mirrors labelled $L_1$ for left mirror and $L_2$ for right mirror in the figure are parallel to each other and 3.0 m apart. A person standing 1.0 m from the right mirror ( $L_2$ ) looks into this mirror and sees a series of images. The second nearest image in the right mirror is situated at a distance:

• A. 2.0 m from the person
• B. 4.0 m from the person
• C. 6.0 m from the person
• D. 8.0 m from the person

Answer 1

Answer: (C)

6.0 m from the person

The nearest image in the right mirror forms with the man as the object.
The second nearest image in the right mirror forms with the nearest image of the man in the left mirror as the object as shown in the figure.
So the distance of the second nearest image from the man is:
$1+5=6m$
