Wave

• P waves are also called longitudinal waves
• P waves are all same width, just different closeness
• One tight curl and one loose curl make one wave
• Transversal waves are also called S waves
• The S wave looks like a real wave
• In S waves there are crests and troughs
• The amplitude is the length from the equilibrium to the crest or trough
• Wave speed = frequency multiplied by wavelength
