Answer 2

Answer:

The correct answer of this question is $m = \frac{37}{12}$

Explanation:

Given - An object is seen through a simple microscope with a focal length of 12 cm.

To find - what will be the angular magnification produced if the image is formed at the near point of the eye which is 25 CM

Now, f = 12cm

m =?

v = -25cm

use the formula

m = 1 + $\frac{D}{f}$

$m = 1 + \frac{25}{12}$

$m = \frac{12 + 25}{25}$

so, $m = \frac{37}{12}$

$m = \frac{37}{12}$  is the angular magnification produced in the image is formed at the near point of the eye?
