Question

If you were using an objective lens that had a magnification of 20X and an ocular lens with a magnification of 8X, then the total magnification would be 160X.

a. True
b. False

Answer 1

The statement is true; the total magnification of using a 20X objective lens with an 8X ocular lens in a microscope is indeed 160X.

Step-by-step explanation:

The statement given is true. In a compound microscope, the total magnification is obtained by multiplying the magnification of the objective lens by that of the ocular lens. Here, the objective lens has a magnification of 20X, while the ocular lens has a magnification of 8X. Therefore, the total magnification achieved when using these two lenses together is:

(20X objective lens) × (8X ocular lens) = 160X total magnification.

This calculation shows that the object being viewed would appear 160 times larger than its actual size. Microscopes with different objective lenses and the standard 10X ocular lens can achieve various levels of magnification.
