Chapter 13, Problem 10STP

To determine

To Find: The magnification of a microscope if the eye piece lens has a magnification of $20$ .

Explanation of Solution

Introduction:

Magnification is the ability of a lens or a mirror to make objects seem larger and making small things visible.

Given:

The magnification of the objective lens in a microscope has a magnification of $30$

The magnification of the eyepiece $20$

Formula:

  $\text{ Magnification of the microscope}=\frac{\text{Magnification power of the objective}}{\text{Magnification power of the eye piece}}$

Substitute $30$ for objective magnification and $20$ for eyepiece in the magnification formula

  $\begin{array}{c}\text{ Magnification of the microscope}=\frac{\text{Magnification power of the objective}}{\text{Magnification power of the eye piece}}\\ =\frac{30}{20}\\ =1.5\end{array}$

Conclusion:

Hence, the magnification is $1.5$
