Chapter 23, Problem 2P

To determine

For what distance should the camera lens be focused?

Answer to Problem 2P

Solution:

6.2 m

Explanation of Solution

As we know that for a flat mirror the image is as far behind the mirror as the object is in front,

Therefore, the distance from object is

$\begin{array}{l}v+u=3.1+3.1\\ =6.2\text{m}\end{array}$

Here, v is image distance and u is object distance
