Lecture 1: Laws of Reflection and Refraction

This video is part of a series from Laser-Tec that introduces learners to geometrical optics. In the video, the laws of reflection and refraction are highlighted. Viewers learn about the difference between light rays and light waves, explore Snell's law of reflection, learn how light rays apply to plane and spherical surfaces and interfaces between different optical media, and become familiar with the index of refraction. The critical angle, total internal reflection, refraction in prisms, the minimum angle of deviation, dispersion of light, and special applications for prisms are also explored. The video recording runs 1:31:57 minutes in length.
