Waves: Longitudinal Waves

The video tutorial uses a slinky to demonstrate longitudinal waves, highlighting how these waves move horizontally rather than vertically. It explains the concepts of compression and rarefaction, where particles collide and separate as the wave progresses. The tutorial also discusses sound waves as a type of longitudinal wave, providing examples such as those produced by airplanes, explosions, and special hammers.
