What is the formula for Actual Size and Magnification?Watch
Magnification = measured size/actual size
I always remeber it as magma
Magnification doesn't have units. The size of the image you usually measure in mm but covert into micrometres or nanometres to work out the actual size.
Pink_Sparkles : how do you convert it? so before I divide the image size by actual size I need to convert it first? I don't know which one to convert...is it the magnification, actual size or image size?
So, you need to measure the picture and convert the units to mm too
1 m = 100 cm = 1000 mm
so 1 x 10^9 nm = 1000 mm
and 1 mm = 1 x 10^6 nm = 1,000,000 nm.
