what is the total magnification of an object if the ocular lens magnification is 20x and the objective lens magnification is 45x?
900x
65x
2.25x
25x

Explanation:

Step1: Recall magnification formula

The total magnification of a microscope is the product of the magnification of the ocular lens and the objective lens. Let $M_{ocular}=20X$ and $M_{objective}=45X$. The formula is $M_{total}=M_{ocular}\times M_{objective}$.

Step2: Calculate total magnification

$M_{total}=20\times45 = 900X$

Answer:

A. 900X
