π Topic Summary
Waves are disturbances that transfer energy through matter or space. They come in different forms, such as mechanical waves (like sound and water waves) that require a medium to travel through, and electromagnetic waves (like light and radio waves) that can travel through a vacuum. Waves play a crucial role in various technologies, like communication and medical imaging, and are also responsible for natural events such as earthquakes and tsunamis.
