A student measured the diameter of a human
capillary on a micrograph. The image measures 5mm
and the student knows the magnification is x1000.
How many micrometres is the diameter of the
capillary
Image
Magnification x Actual
Image = 5mm
Image = 5000µm
Magnification = 1000
Image ÷ magnification = actual
5000 ÷ 1000
= 5µm
