You want to examine the hairy details of your favorite pet caterpillar, using a lens of focal length 8.9 cm 8.9 cm that you just happen to have around. With the lens close to your eye and the animal at the lens's focal point, what angular magnification M M do you achieve? Assume your near point is at 25.0 cm.

Answer:

The angular magnification is [tex]M = 2.808[/tex]

Explanation:

From the question we are told

           The focal length is  [tex]f = 8.9cm[/tex]

          The near point is [tex]n_p = 25.0cm[/tex]

The angular magnification is mathematically represented as

                          [tex]M = \frac{n_p}{f}[/tex]

Substituting values

                        [tex]M = \frac{25}{8.9}[/tex]

                           [tex]= 2.808[/tex]
