Reflection and Refraction in General Physics - Lesson 22.1

Explore the fundamental concepts of reflection and refraction in this comprehensive physics lesson. Begin with the Law of Reflection, stating that the angle of incidence equals the angle of reflection. Delve into refraction, examining how light bends when passing between different media. Learn about the index of refraction and its relationship to light speed in various materials. Master Snell's Law of Refraction to calculate refraction angles based on different media's refractive indices. Practice solving reflection and refraction problems. Investigate total internal reflection and its critical angle. Conclude with an introduction to dispersion, understanding how different wavelengths of light refract at slightly different angles, leading to phenomena like white light separation through a prism.
