Chapter 35: Q. 26 (page 1017)

In figure $p 35.26$ , parallel rays from the left are focused to a point at two locations on the optical axis. find the position of each location, giving your answer as a distance left or right of the lens.

Short Answer

Expert verified

The position of each location, giving your answer as a distance left or right of the lens is $S^{'} = - 1 c m$ .

Step by step solution

Given information

We need to find the image distance for the mirror .

Simplification

By using the formula, we have to solve $S^{'}$

$S^{'} = \frac{S f}{S - f}$

Here, $S$ is the distance between matter, $f$ is the focal length of the mirror and $S'$ is the position of the location.

Substituting the value in equation,

$S^{'} = \frac{(3 c m) + (- 1.5 c m)}{(3 c m) - (- 1.5 c m)}$

$S^{'} = \frac{- 4.5 c m^{2}}{4.5 c m}$

$S^{'} = - 1 c m .$
