Traveling Waves & Wave Equation Sending a pulse down a string T = tension µ = mass/length
Wave Equation: F =ma For small angles: Force mass accceleration
Wave Equation: Solutions Any function y(x,t) will satisfy wave eq as long as x and t appear inthe argument in the combination:
Wave Equation Examples Electric (E) or magnetic (B) field propagating in space from an oscillating charge (Light) Current (I) or voltage (V) propagating in a coax cable c - is the speed of light The quantum-mechanical probability amplitude to find a particle at a certain location in space also satisfies a wave equation - Schroedinger’s Equation
Standing Waves Reflected pulse But if we have a incident sinusoidal travelingwave and a reflected sinusoidal wave:
