Question

The width of a cell is 0.025mm; under the microscope it is 10mm. What was the magnification?
​

Answer 1

Answer: 400

Explanation:

To calculate the magnification, you can use the formula:

Magnification = Size of Image / Size of Object

In this case, the size of the object (width of the cell) is given as 0.025 mm, and the size of the image (as observed under the microscope) is 10 mm.

Magnification = 10 mm / 0.025 mm = 400

Therefore, the magnification is 400.
