Explanation:
Detailed explanation-1: -Actual size = image size / magnification. Image size = magnification x actual size.
Detailed explanation-2: -To calculate the actual size of a magnified specimen, the equation is simply rearranged: Actual Size = Image size (with ruler) ÷ Magnification.
Detailed explanation-3: -Working out magnification: Measure the scale bar image (beside drawing) in mm. Convert to µm (multiply by 1000). Magnification = scale bar image divided by actual scale bar length (written on the scale bar).
