... "bunching" of the coils will pass along the spring. The individual coils only go forwards and back a little way. Sound waves are examples of longitudinal waves. What are Transverse waves? Transverse waves vibrate sideways. Think of waves over water. These are transverse waves. The wave travels across the surface of the water BUT the individual molecules of water on the surface go UP and DOWN, not sideways. Watch a piece of wood on the water. It bobs up and down. The vibrations are at 90 degrees to the direction of travel. Other examples of transverse waves are waves along a rope (think how you make the wave - by moving the rope sideways) and all the electromagnetic spectrum waves - radio waves, microwaves, infra red, visible light, ultra violet, X-rays and gamma rays. What is a seismic wave? These are waves from vibrations in the Earth (core, mantle, oceans), which also occur on ...
