How we use light to see.. To the physicist, the colors of things are not in the substances of the things themselves.. Color is in the eye of the beholder and is provoked by the frequencies of light emitted or reflected by things.. Mr. . . Dvorsky. SNC2D1. Review of last chapter. From the last chapter, we know how light behaves when it travels in space or in the air – i.e. it travels in a straight line.. When light strikes a plane mirror, the angle of incidence = the angle of reflection. . What has happened in each example and why?. I think this is called.... It happens when.... It happens because.... The air is.... The water is.... The light usually. travels...but when it hits water.... By Kristine. Optical devices. An optical device is any technology that uses light. An optical device can be as simple as a mirror, or as complex as the Hubble Space Telescope.. Microscopes. Hans and Zacharias Jansen of the Netherlands first built a microscope in about 1595..
