Explain the working of a Galilean Telescope?
A Galilean telescope, invented by Galileo Galilei, uses a simple lens arrangement to magnify distant objects. It consists of a convex objective lens, which gathers light from a distant object to form an inverted image, and a concave eyepiece lens, which intercepts the light before the image fully forms. The concave eyepiece then creates an upright virtual image that appears magnified to the viewer.
This design allows the Galilean telescope to provide an upright image without additional prisms or lenses. However, its field of view is relatively narrow, and it offers lower magnification compared to more advanced telescopes. Despite these limitations, the Galilean telescope was revolutionary, allowing Galileo to make groundbreaking astronomical observations, including the moons of Jupiter.
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 of Telescope = Focal Length of Objective/Focal Length of Eyepiece to calculate the Magnifying Power of Telescope, Magnifying Power of Galilean Telescope when Image Forms at Infinity formula is defined as the ratio of the focal length of the objective lens to the focal length of the eyepiece lens, which determines the magnification of an object when its image is formed at infinity. Magnifying Power of Telescope is denoted by Mtele symbol.
