Answer:
The magnification is 133X
Explanation:
For a refractor telescope using convex lenses, the overall magnification os calculated as by dividing the focal length of the objective by that of the eyepiece.
[tex]M = \frac{f(obj)}{f(eye)}[/tex]
So:
[tex]M = \frac{16 m}{12 cm}[/tex]
Care must be taken with the units, in this case they are in meters and centimeters, they should be converted into the same unit before calculating:
[tex]M = \frac{16 m}{0.12 m} = 133[/tex]
