Electromagnetic Waves: Properties and Polarization

This lecture covers the properties of electromagnetic waves, including their propagation, polarization, and relationship between electric and magnetic fields. The instructor explains how the electric and magnetic fields oscillate perpendicular to the direction of wave propagation, leading to transverse waves. The lecture also delves into the concept of polarization, where the direction of the electric field determines the behavior of light passing through polarizers. Practical applications of polarization, such as polarizing filters in photography and sunglasses, are discussed. The relationship between electric field intensity and light intensity is highlighted, emphasizing how our eyes detect electromagnetic waves.
