Question

What is the angular magnification of a microscope using an objective with a magnification of 23.7 and an ocular with a magnification of 9.90?

Answer 1

Answer 2

Solution:

The total angular magnification ($M_{\text{total}}$) of a microscope is the product of the objective lens magnification ($M_{\text{obj}}$) and the ocular (eyepiece) magnification ($M_{\text{ocular}}$):

$$M_{\text{total}}=M_{\text{obj}}\times M_{\text{ocular}}$$

Given:

• $M_{\text{obj}}=23.7$

• $M_{\text{ocular}}=9.90$

Calculation:

$$M_{\text{total}}=23.7\times 9.90=234.63$$

Answer:

The angular magnification of the microscope is 234.6× (rounded to one decimal place).
