Chapter 35: Q. 33 (page 1018)

Yang can focus on objects $150 c m$ away with a relaxed eye. With full accommodation, she can focus on objects $20 c m$ away. After her eyesight is corrected for distance vision, what will her near point be while wearing her glasses?

Short Answer

Expert verified

Near point be while wearing her glasses is $S = 23.07 c m$ .

Step by step solution

Given Information.

We need to find out yang's near point while wearing glasses after her sight is corrected for distance vision.

Simplify

As we know the value of:

$f = 150 c m$ .

As we can conclude that the yang nearsighted. With glasses and wears a virtual image focused to her far point, $\frac{1}{f} = \frac{1}{- 150} + \frac{1}{\infty}$ and also given the focal length of $- 150 c m$ .

We know the image has a form at $20 c m$ away for her to see clearly, and using that image to distance to calculate a new near point and also we can follow the way:

$S = \frac{(- 150) (- 20)}{(- 20) - (- 150)} S = \frac{3000}{130} S = 23.07 c m$ .

Here, $S$ is the near point.
