Science of Light

One of the first scientists to study light in a scientific way was Alhazen (965-1038). At the time, most people believed that light came out of the eyes and shone onto objects, so that we could see them. Alhazen worked out the correct explanation - that light from a light source, such as the Sun or a candle, reflected off objects and went into the eye. He also studied colored lights, mirrors and lenses. His work helped later scientists to develop the microscope, telescope and other optical, or light-based, devices. (World of Science)
