Refraction is a captivating phenomenon that occurs when light travels from one medium to another, causing it to change direction. This intriguing behavior of light has been studied and harnessed by scientists, enabling the development of various optical devices and contributing to our understanding of the nature of light itself.
Before we proceed, may I kindly ask you to take a moment to solve some crosswords on the topics of Angles, Atmosphere, Mirrors, Rainbow, Reflection Of Light, Temperature, Light, Spectroscopy, Water, and Air and also solve some MCQs on the topics of advanced sunrise and delayed sunset, refractive index, atmosphere, concave lens, convex lens, dew, diffraction, light, light sources, microscope, optics, rainbow, reflection of light, refraction of light, vacuum, white light, air, water?
At its core, refraction is the bending of light as it passes through different substances, such as air, water, glass, or any transparent material. The extent of bending depends on the change in the speed of light as it moves from one medium to another. The phenomenon is governed by Snell’s Law, which mathematically describes how light behaves at the interface between two media with different refractive indices.
