The magnifying power of this telescope is 12,5.
What is a telescope?
The telescope is an optical instrument that aims to allow the observation of large objects at long distances, such as galaxies, stars and planets. It consists of two parts: the objective, which can be a lens or a curved mirror, and the eyepiece, made up of a set of lenses.
With that being said and knowing that:
The focal length of the objective of a telescope (fo) = 75cm; The focal length of the eyepiece of a telescope (fe) = 6cm.
[tex]M = \frac{fo}{fe}[/tex]
Changing the values:
[tex]M = \frac{75}{6} = 12,5[/tex]
So, The magnifying power of this telescope is 12,5.
