Media Summary: Review of the Maxwell's equations leading up to the derivation of the electromagnetic wave equation. After deriving the wave equation for sound, we discuss what determines the wave speed of sound in gas, liquid and solid. Brief discussion on extending the wave equation to 3D and interpreting the 3D plane wave solution.

Review of the Maxwell's equations leading up to the derivation of the electromagnetic wave equation. After deriving the wave equation for sound, we discuss what determines the wave speed of sound in gas, liquid and solid. Brief discussion on extending the wave equation to 3D and interpreting the 3D plane wave solution. example problem for the doppler effect in which both the source and observer are moving. Develops the wave equation for sound waves. Math preliminary about the complex exponential.
couple numerical examples with the decibel scale. Photoelectric effect and blackbody ratiation as a motivator for quantization of EM energy. numerical example of the double slit, given the spacing of adjacent bright fringes to find the spacing of the slits. Shows how the plane wave (transverse electromagnetic wave) agrees with Maxwell's equations, and develops the wave ...
