Chapter 26: Q37PE (page 957)

A 7.5 $脳$ binocular produces an angular magnification of-7.50 , acting like a telescope. (Mirrors are used to make the image upright.) If the binoculars have objective lenses with a 75.0cm focal length, what is the focal length of the eyepiece lenses?

Short Answer

Expert verified

The focal length of the eyepiece lensesis $f_{e} = 0.1 m$ .

Step by step solution

Concept Introduction

Magnification is the process of expanding something's perceived size rather than its true size. This expansion is measured by a numerical value known as "magnification." When this value is less than one, it denotes a size decrease, often known as minification or de-magnification.

Calculating the focal length of the eyepiece lenses

The angular magnification is supplied by, as we said before in the idea session.

$M = \frac{胃'}{胃} = \frac{f_{0}}{f_{e}}$

Rearrange the eyepiece lenses and solve for the focal length: such that,

$f_{e} = \frac{f_{0}}{M} = \frac{0.75 m}{- 7.5} = 0.1 m$

Therefore, the focal length of the eyepiece lenses is $f_{e} = 0.1 m$
