GCSE Physics - Refraction of waves #63

The video tutorial explains the concept of refraction, where light waves change direction when passing from one medium to another due to differences in density. It covers how to draw ray diagrams, showing the path of light as it enters and exits a medium like glass. The tutorial also discusses the relationship between wave speed, frequency, and wavelength, emphasizing that frequency remains constant while wavelength changes. Finally, it explores how different wavelengths of light are refracted by varying amounts, leading to dispersion in a triangular prism, creating a rainbow effect.
