After deriving the wave equation for sound, we discuss what determines the wave speed of sound in gas, liquid and solid. Review of the Maxwell's equations leading up to the derivation of the electromagnetic wave equation. Brief discussion on extending the wave equation to 3D and interpreting the 3D plane wave solution. Develops the wave equation for sound waves. numerical example of the double slit, given the spacing of adjacent bright fringes to find the spacing of the slits. example problem for the doppler effect in which both the source and observer are moving.
Discuss briefly different examples of waves. Developes the form of the standing wave with both cosine and the complex exponential. Introduces the doppler effect and derive the formula for the doppler effect for sound. Shows how the plane wave (transverse electromagnetic wave) agrees with Maxwell's equations, and develops the wave ...
