An image of a wire grid is focused onto the white metal receiving screen which has a squared paper insert to aid measurements. The wooden optical bench allows for fairly precise experiments in the classroom and consists of a 1.5 meter rail on which carriages are placed against a millimeter scale. Holders for light sources, lenses and screens are placed on the apparatus so that image formation can be observed. | |
