¨A converging lens has a positive focal length
¨It focuses beams of light
through a focal point, a distance f from the centre of the lens
¨When an object is placed
beyond the focal point, you get an inverted, real image. This is how photography works
¨When an object is placed
between the lens and the focal point, you get an upright, virtual image. This is how magnifying lenses
work
