Lens Worksheet 1: Magnifying or reducing glass?

Look at graph paper through a selection of converging

and diverging lenses.

Is the grid magnified or reduced? Put a positive number

to show a magnification (e.g. +3 magnifies more than

+1) and a negative number to show a reduction (e.g. -2

reduces more than -1)
