Transverse Waves
Particles move perpendicular to wave direction (Ripples, Vibrations in guitar string, Electromagnetic Waves, Seismic S-Waves) 2 Dimensions CAN be polarised or aligned (Troughs and crests)
Longitudinal Waves
Particles move parallel to wave direction (Sound waves in air, Primary waves of earthquake, ultrasound, vibration of spring, fluctuations in gas, tsunami waves) 1 Dimension CANNOT be polarised or aligned (Rarefractions and compressions)
Oscillation DIrection
Propagation Direction
V= f x w
Velocity Formula
Velocity (m/s)
Distance a wave travels per second
Frequency (Hz)
Number of crests per second
Wavelength (m)
Distance between two successive crests or troughs
Wavefront
Imaginary Line
