|
Magnification = Strength of lens/ image size
|
|
|
Magnification = image size/ real size
|
|
|
Magnification = image size x real size
|
|
|
Magnification = real size/ image size
|
Detailed explanation-1: -Magnification = image size / actual size. Actual size = image size / magnification.
Detailed explanation-2: -The ratio of the height of an image ( ) to the height of an object ( ) is defined as the magnification of a lens. Also, magnification is equal to the ratio of image distance to that of object distance. The formula is m = h i h o .
Detailed explanation-3: -To calculate the actual size of a magnified specimen, the equation is simply rearranged: Actual Size = Image size (with ruler) ÷ Magnification.
Detailed explanation-4: -The magnifying power of a compound microscope is also equal to the product of the magnification produced by the objective lens and magnification produced by the eye lens. i.e. m=mo×me.
Detailed explanation-5: -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).
