Physics 111: Optical Instruments Lecture Physics 111 Advanced Laboratory. Professor Sumner Davis This video accompanies several experiments in the course, providing students with background on optics, optical instruments, rays, wave fronts, and Snell's Law. You will learn how to move light where and how you want, how light bends, and why it bends. Like reflection, refraction involves the angles that the incident ray and the refracted ray make with the surface. Unlike reflection, refraction depends also on the media through which the light rays are travelling. This dependence is made explicit in Snell's Law via refractive indices, numbers that are constant for given media. http://advancedlab.org
