Physics 111: Optics and Optical Phenomena

24 Lessons Calculating...

We can use light rays to model the behaviour of light relative to mirrors, lenses, telescopes, microscopes, and prisms. The study of how light interacts with materials is called optics. When dealing with light rays, we are usually interested in the shape of a material and the angles at which light rays hit it. From these angles, we can determine, for example, the distance between an object and its reflection. We call these methods geometrical optics. In this tutorial, we study geometrical optics.

Many people are using solar power as a source of energy for their homes. Solar power can be used to heat water or to supply electricity. Have you ever noticed solar panels on homes and buildings? Have you ever wondered how solar energy is converted to electrical energy? In this tutorial, we examine the process that is used to achieve this energy conversion.
