Question

If the magnification power on your microscope's objective was 40X and the magnifying power on the eyepiece was 10X, the total magnification would be _____.
a.50X
b.30X
c.400X
d.40X

Answer 1

The answer is C) 400X. Hope I helped.

Answer 2

Answer:

Total magnification, m = 400 X

Explanation:

It is given that,

Magnification power on microscope's objective, m₁ = 40 X

Magnifying power on the eyepiece, m₂ = 10 X,    

We have to find the total magnification. Total magnification of an image is given by the product of microscope's objective and magnifying power of the eyepiece i.e.

m = m₁ × m₂

m = 40 X × 10 X

m = 400 X

So, the total magnification would be 400 X. Hence, the correct option is (c) "400 X".
