Can you design a refracting telescope using two convex lenses? What are the required conditions for such a telescope?
Homework Answers
This type of telescope is called a refracting telescope. Most refracting telescopes use two main lenses. The largest lens is called the objective lens, and the smaller lens used for viewing is called the eyepiece lens.

9. A simple telescope can be constructed from two convex lenses. Consider a telescope that uses a 500 mm lens (focal length of 500 mm) for the objective lens and a 150 mm lens for the eye piece. 1. How far apart must the lenses be placed to view an object that is 100 m away (from the objective lens) and appears to be 20 cm in front of the eyepiece lens? 2. What magnification does the telescope produce for...

Galileo's Telescope Galileo's first telescope used a convex objective lens with a focal length f=1.7m and a concave eyepiece, as shown in the figure. (Figure 1)When this telescope is focused on an infinitely distant object, and produces an infinitely distant image, its angular magnification is +3.0. A. What is the focal length of the eyepiece? in cm b. How far apart are the two lenses?

You want to build a Galilean Telescope. Your Objective lens is convex with a focal point at 35cm. The Eyepiece is 12.5cm concave lens. Draw a diagram of the placement of the lenses showing their focal lengths in the diagrams showing the distance between the 2 lenses. Calculate the magnification of the device, show all steps.

Two lenses are mounted in a tube such that the distance between them can be varied. This device can be used as either a telescope or a compound microscope. One lens (the objective) has a focal length of 52.5 cm. (a) Find the focal length of the second lens (the eyepiece) such that the magnification |m|=si sN/(fobj feyepiece) of the microscope is the same as the magnification |m|=fobj/feyepiece of the telescope. Assume the distance between the two lenses of the...

1) What is the total magnification of a refracting telescope having an objective and eyepiece lens of focal lengths 30.0 cm and 0.40 cm respectively? 2) If the focal lengths of both the objective lens and the eyepiece were doubled in a compound microscope, what would be the change in the magnification? 3) If you wish to look at Mars or any planet with a telescope, what sort of objective lens and eyepiece lens should you use? A. Objective long...

Please answer, thank you.
Part A The largest refracting telescope in the world is at Yerkes Observatory in Wisconsin. The objective lens is 1.02 m in diameter and has a focal length of 19.4 m. Suppose you want to magnify Jupiter, which is 1.38x10 km in diameter, so that its image subtends an angle of (about the same as the moon) when it is 6.28x109 km from earth. What focal length eyepiece do you need? A O O ? IVO...
