A super Flash demonstration from Freezeray on normal sight, short-sightedness and long-sightedness. It also shows how varying the focal length of a corrective lens will give a clear image on the retina of the eye.

This IWB teaching aid demonstrates by plotting the paths of the incident and reflected rays how the image of an object is formed in a mirror.

This simulation from Freezeray shows how a beam of light is reflected by a plane mirror. The angle of incidence can be varied by dragging the light source.

This teaching resource is designed to show the Law of Reflection. The angle of the light source can be varied and there is an optional protractor to measure the angles of incidence and reflection.
