Electromagnetic Nature of Light — A brief history of light.
Let us begin this lecture which has roughly two parts; 1. the history of light and its understanding through the centuries and 2. the electromagnetic nature of light A brief history of light Various optical devices and optical phenomena have been known since close to 4000 years. The optical devices of ancient time includes mirrors, burning…

Spherical harmonic waves
In our lecture — VIII, we worked out the form of plane harmonic traveling waves. Note that soon we will have to a. address the concept of wave profile and b. how to convert a wave profile into its corresponding time-dependent or traveling form. But before we do that here is yet another general form of…
