STEP 0: Pre-Calculation Summary

Formula Used

Magnifying Power = Focal Length of Objective/Focal Length of Eyepiece
M = f_o/f_e
This formula uses 3 Variables

Variables Used

Magnifying Power - Magnifying Power or the extent to which the object being viewed appears enlarged is related by the geometry of the optical system.
Focal Length of Objective - (Measured in Meter) - The Focal Length of Objective is the focal length of the lens in front known as the objective lens uses to focus an image.
Focal Length of Eyepiece - (Measured in Meter) - The Focal Length of Eyepiece is the distance from the principal plane of the eyepiece where parallel rays of light converge to a single point.

STEP 1: Convert Input(s) to Base Unit

Magnifying Power of Galilean Telescope when Image Forms at Infinity Formula

Magnifying Power = Focal Length of Objective/Focal Length of Eyepiece
M = f_o/f_e

Explain the working of a Galilean telescope.

It consists of a convergent lens as objective (i.e., the lens that forms the image); and its eyepiece (or ocular), placed in front of the focus, is a divergent lens. An upright image is produced. This simple refracting telescope is still used in modern opera glasses, which are low-powered binoculars.

What are the uses of a Galilean telescope ?

The galilean telescope is used a convergent (plano-convex) objective lens and a divergent (plano-concave) eyepiece lens.

How to Calculate Magnifying Power of Galilean Telescope when Image Forms at Infinity?

Magnifying Power of Galilean Telescope when Image Forms at Infinity calculator uses Magnifying Power = Focal Length of Objective/Focal Length of Eyepiece to calculate the Magnifying Power, Magnifying Power of Galilean Telescope when Image Forms at Infinity is defined as the ratio of the angle subtended at the eye by the image formed at the least distance of distinct vision to the angle subtended at the eye by the object lying in infinity. Magnifying Power is denoted by M symbol.
