Doppler EffectThe Doppler effect is a change in apparent frequency of a wave due to the relative motion of wave emitter and detector.
EM Waves from an Accelerating ChargeThe emission of light, or electromagnetic waves, due to accelerating charges, is how we can see objects.
Electromagnetic Plane WavesPlane waves is the simplest approximation to electromagnetic radiation.
PolarizationThe polarization of electromagnetic waves describes the direction of the oscillating electric, or magnetic, field.
Wave EquationThe motion of a wave can be determined by considering the forces on the individual elements of the material through-which the wave travels.
Oscillator ChainThe Oscillator Chain provides a microscopic physical model for the oscillatory motion in a transverse wave.
Non-Linear WavesThe simple wave-equation can be expanded to include terms to model more complicated physics.
SolitonsSolitons give a model for wave pulses that maintain their shape as they propagate.
