Angular Magnification of a Telescope

The angular magnification of a telescope is defined as the ratio of the objective lens's focal length to that of the eyepiece. This formula is a fundamental concept in optics and is used to determine how much larger an object appears when viewed through a telescope as compared to the naked eye. A higher magnification factor suggests a larger image of the observed object. This principle is widely applied in astronomical and terrestrial telescopes to allow observers to see distant objects in greater detail.
