Refraction

The video tutorial explains the concept of refraction, a phenomenon where light bends as it passes from one medium to another of different density. It illustrates everyday examples like rainbows and the bending of objects in water. The tutorial delves into the science behind refraction, including the index of refraction and how prisms disperse light into a spectrum of colors. It also touches on the broader application of refraction in various types of waves, such as seismic and sound waves, and its role in understanding Earth's interior.
