1
Traveling Waves & Wave Equation Sending a pulse down a string T = tension µ = mass/length

2
Wave Equation: F =ma For small angles: Force mass accceleration

3
Wave Equation: Solutions Any function y(x,t) will satisfy wave eq as long as x and t appear in the 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 - Schroedingers Equation
