Electromagnetic waves and optics form a fundamental part of physics, bridging the study of light with the broader spectrum of electromagnetic radiation. Electromagnetic waves are oscillations of electric and magnetic fields that travel through space, carrying energy without the need for a physical medium. They encompass a wide range of phenomena, from radio waves and microwaves to visible light, ultraviolet rays, and X-rays. Optics, on the other hand, focuses specifically on the behavior and properties of light, including reflection, refraction, diffraction, and interference. Together, these topics provide the foundation for understanding how energy is transmitted across space, how light interacts with matter, and how technologies such as lenses, lasers, fiber optics, and imaging systems are developed. This introduction highlights the importance of electromagnetic waves and optics in both scientific exploration and practical applications, from communication systems to medical diagnostics.
This lecture is part of PHY 304 ELECTROMAGNETIC WAVES AND OPTICS in the Physics department. The course has 30 recorded lectures across 10 series, all free to watch.
