Reflection

The video explains the concept of wave reflection, where waves return to their original medium after encountering a boundary between two different media. It highlights familiar examples such as light reflecting off mirrors, glass, and water, and extends the concept to radio waves, sound echoes, and compression waves from earthquakes.
