Question

the total magnification achieved using a 10× objective lens with a 10× eyepiece lens is 20×. true or false

Explanation:

Step1: Recall magnification formula

Total magnification ($M_{total}$) of a microscope is the product of the magnification of the objective lens ($M_{objective}$) and the magnification of the eyepiece lens ($M_{eyepiece}$), i.e., $M_{total}=M_{objective}\times M_{eyepiece}$.

Step2: Calculate total magnification

Given $M_{objective} = 10\times$ and $M_{eyepiece}=10\times$, then $M_{total}=10\times10 = 100\times$, not $20\times$.

Answer:

False
