To use a magnifying lens, place the object to be enlarged on the bench. Hold the magnifying lens on one hand and while closing one eye, move the lens towards the object until the image comes into clear focus.
If a magnifying lens is used to make a drawing of a specimen, the magnification of the drawing will have no relation with the size of the drawing.
The magnification of the drawing can be calculated using the formula shown below.
Drawing magnification
Length of drawing divided by Length of the actual object
The sign of “times” must come before the magnification value like X10, X5, X15 .
