In this lesson, we will learn how to calculate the imaging properties of reflecting, refracting, and compound optical systems used in telescopes.
Sample Question Videos
What is the angular magnification of a telescope that has a 100 cm focal length objective and a 2.50 cm focal length eyepiece?
A 7.5x pair of binoculars produces an angular magnification of , acting like a telescope (where mirrors are used to make the image upright). If the binoculars have objective lenses with a focal length of 75.0 cm, what is the focal length of the eyepiece lenses?
A large reflecting telescope has an objective mirror with a radius of curvature of 10.0 m. What angular magnification does it produce when an eyepiece of focal length 3.00 m is used?
