1. Traveling Waves

2. Wave Equation For small angles: Force mass accceleration

3. Wave Equation Any function y(x,t) will satisfy wave eq as long as x and t appear inthe argument in the combination: tension velocity mass/length

4. Wave Equation Any function y(x,t) will satisfy wave eq as long as x and t appear inthe argument in the combination:

5. Solutions to Equation The disturbance y(x,t) performs simple harmonic motion aboutequilibrium in t (for fixed x) or x (for fixed t).

6. Wave Equation Other quantities satisfying wave equation 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
