Microscope Total Magnification Calculation
What is the total magnification of a high-power objective lens combined with a 10x eyepiece?
1) 200x magnification
2) 300x magnification
3) 400x magnification
4) 500x magnification
The correct answer is Option C) 400x magnification.Answer:
The total magnification of a microscope is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece.
In this case, the high-power objective lens has a magnification of 40x, and the 10x eyepiece provides a magnification of 10x.
When the high-power objective lens (also known as the "high dry" lens) with a magnification of 40x is combined with a 10x eyepiece, the total magnification is calculated as follows:
Total magnification = Objective lens magnification × Eyepiece magnification
Total magnification = 40x × 10x = 400x
Therefore, the total magnification of a high-power objective lens combined with a 10x eyepiece is 400x.
