Sound Waves and Their Properties

The video explains how sound waves are disturbances that transfer energy through vibrations in a medium like air, walls, or water. It discusses how sound waves can be absorbed, transmitted, or reflected, leading to phenomena like echoes and reverberation. Animals like dolphins and bats use echolocation to navigate, while humans use sonar technology. The video also covers how the pitch and volume of sound depend on the frequency and amplitude of the waves.
