Electromagnetic Waves: Superposition and Interference

This lecture covers the radiation field of an oscillating dipole, intensity, and energy radiated. It also discusses how to radiate electromagnetic waves at high energy, superposition of waves, Huygen's principle, interference at double slit, interference of counter-propagating waves, time evolution of standing e-m wave, spatial variation of Poynting vectors, interference and energy density. The instructor explains how accelerated charges emit electromagnetic waves, the concept of superposition, and the interference patterns resulting from wave interference.
