Question

what is the total magnification of a specimen using the 40x objective?

the total magnification would be 4x.
the total magnification would be 40x.
the total magnification would be 400x.

Explanation:

Identify the formula for total magnification

$$ \text{Total Magnification} = \text{Ocular Lens Magnification} \times \text{Objective Lens Magnification} $$

Determine the standard values

$$
LATEXBLOCK0
$$

Calculate the final product

$$ \text{Total Magnification} = 10 \times 40 = 400\text{X} $$

Answer:

• The total magnification would be 4X.
• The total magnification would be 40X.
• The total magnification would be 400X. (Correct answer)
