Waves: Reflection

The video tutorial explains the four main ways waves interact with mediums: reflection, refraction, diffraction, and interference. It uses the example of an echo in a valley to illustrate reflection, where sound waves bounce back after hitting an object. The tutorial further details the concept of reflection, describing incident and reflected waves, and provides examples such as mirrors and water reflections.
