4. Refraction of Light at Plane Surfaces

Refraction is the bending of light when it passes from one transparent medium to another. This concept is crucial for understanding the behavior of light in various applications such as lenses and optical instruments. The chapter explores the laws of refraction, the refractive index, and practical applications through examples and illustrations.
