We use microscopes to look at very small things. The microscope magnifies the image so that it appears larger than it would with just our eyes.
Microscopes use lenses to magnify the image of a biological specimen so that it appears larger.
The magnification of a lens on a microscope is shown by a multiplication sign followed by the amount the lens magnifies, eg ×10.
The formula to calculate magnification is:
If the size of a cell seen down the microscope is 5 mm and the real size of the object is 0.005 mm, what is the magnification?
= 5 ÷ 0.005
The magnification is therefore ×1,000.
