Magnification Produced by Lenses

The most important feature of lenses (for which they are produced) is the magnification they provide. The approach is the same as magnification in curved mirrors. This means we can use two formulae for the calculation of magnification:

M = himage/hobject

where h stands for height, and

M = dimage/dobject

For example, if we take the height of the object in the previous example equal to 3 cm, we can work out the image's height by combining the two formulae of magnification:

himage/hobject = dimage/dobject

Substituting the known values, we obtain for the image's height:

himage/3 cm = 24 cm/12 cm

Thus,

himage = 6 cm
