Understanding Waves

The video tutorial introduces the concept of waves, explaining how they transport energy without moving matter. It distinguishes between mechanical waves, which require a medium, and electromagnetic waves, which do not. Examples of mechanical waves include waves on a rope and water ripples, while electromagnetic waves include radio and microwave signals. The tutorial concludes with a call to action for viewers to engage with the content.

What is the initial example used to explain waves?
