Question

The magnification of a light microscope can be found by multiplying the power of the eyepiece by the power of the objective lens. Calculate the magnifications of a microscope that has an 8X eyepiece, and 1OX and 40X objectives.

Answer 1

Answer: For 10X objective =80X

For 40X objectives =320 X

Explanation: The magnification of a light microscope can be computed by multiplying the power of the eyepiece by the power of the objective lens.

• For the 10X objective = power of eyepiece × power of objective lens

= 8X × 10X

= 80X

• For the 40X objective = power of eyepiece × power of objective lens

= 8X × 40X

= 320X

Answer 2

To calculate the total magnification of a microscope, we multiply the magnification of the eyepiece by the magnification of the objective.

For the 10X objective:

Total magnification = Eyepiece magnification x Objective magnification
Total magnification = 8X x 10X
Total magnification = 80X

So the total magnification for the combination of the 8X eyepiece and the 10X objective is 80X.

For the 40X objective:

Total magnification = Eyepiece magnification x Objective magnification
Total magnification = 8X x 40X
Total magnification = 320X

So the total magnification for the combination of the 8X eyepiece and the 40X objective is 320X.
