Chapter 18, Problem 92A

To determine

The position of the imagerelative to the eyepiece lenses in the binoculars.

Answer to Problem 92A

The image should be in between the eyepiece lens and its focal point.

Explanation of Solution

Introduction:

Binocular are generally used to observe the distant objects. Binoculars is made from two telescopes that are fixed side-by-side and pointing in the same direction so that an observer can use both the eyes at the same time to see the distant objects. Hence binoculars can give three dimensional view of the distant objects.

In binoculars two telescopes are mounted side by side. Both are refracting telescopes. Hence in order to see the magnified image of an object, the image must be in between the eyepiece lens and its focal point.
