Question

Why is the total magnification of a microscope whith two lenses when one lens as a magnification of 15x and the other lens has a magnification of 30x?
A. 15x
B. 45x
C.30x
D.450x

Answer 1

Answer:

To calculate the total magnification (TM), take the objective lens multiply by the eyepiece lens. In this case, one of the given values must be the objective while the other the eyepiece lens. So;

TM = Eyepiece lens x objective lens whereby in this case

TM = 15 x 30

      = 450x

Hope this helps.

Answer 2

Given - Magnification of lenses: 15x and 30x

Find - Total magnification of the microscope

Solution - Total magnification of microscope can be calculated by multiplying the magnification power of two lenses given in question.

Thus, the total magnification of lenses will be - 15*30

The total magnification of lenses or microscope = 450x

Therefore, the microscope has the power to magnify the sample 450 times. So, the correct answer is option D. 450x
