Description

This lecture covers the concepts of AC power and waves, focusing on the analysis of series RLC circuits and the delivery of average power. It also delves into the nature of electromagnetic waves, wireless communication, and the interaction of waves with matter. The instructor explains wave equations, energy transmission, and the electromagnetic spectrum, emphasizing the emission of electromagnetic waves and standing wave phenomena. Through practical examples and historical insights, students explore the applications of electromagnetic waves in wireless technology and communication. The session concludes with a discussion on wave propagation and interference effects, including demonstrations of wave nature through water wave interference and noise-cancellation headphones operation.
