Chapter 13, Problem 38R

To determine

To Find: The magnification of the telescope.

Answer to Problem 38R

The magnification of the telescope is $100$ .

Explanation of Solution

Given:

Focal length of objective is $1\text{m}$

Focal length of the eyepiece is $1\text{cm}$

Introduction:

The magnification is the focal length of the telescope divided by the focal length of the eye piece, in millimeters.

Formula:

Magnification of telescope is

  $\text{m}\text{=}\frac{\text{Focal length of objective}}{\text{Focal length of the eyepiece}}$ ... (1)

Substitute $1\text{m}$ for focal length of objective, and $1\text{cm}$ for the focal length of the eyepiece in equation (1).

  $\begin{array}{c}\text{m}\text{=}\frac{\text{1}\text{m}}{\text{1}\text{cm}}\\ =\frac{\text{100}\text{cm}}{\text{1}\text{cm}}\\ =100\end{array}$

Conclusion:

Hence, the magnification of the telescope is $100$ .
