Question

1.2 if the magnification power of the microscope is 600x and the magnification of the eyepiece is 10x, then the magnification of the objective lens must be:
A. 6x
B. 0.6x
C. 6000x
D. 60x

Answer 1

To find the magnification of the objective lens, we can use the formula for total magnification of a microscope:

\[
\text{Total Magnification} = \text{Eyepiece Magnification} \times \text{Objective Magnification}
\]

Given:
- Total Magnification = 600x
- Eyepiece Magnification = 10x

Let \(O\) be the magnification of the objective lens. We can set up the equation:

\[
600 = 10 \times O
\]

To find \(O\), we can rearrange the equation:

\[
O = \frac{600}{10} = 60
\]

Thus, the magnification of the objective lens is:

\[
\text{Objective Magnification} = 60x
\]

Therefore, the correct answer is:

**D. 60x**
