This lecture covers the propagation of electromagnetic waves in linear matter, discussing absorption, diffusion, reflection, and refraction phenomena. It explains the impact of refractive index, wavelength, and speed on wave propagation, as well as the laws of reflection and refraction. The lecture also delves into dispersion in different media, the group and phase speeds of waves, and the critical angle for total internal reflection. Examples of total internal reflection interfaces and optical fiber properties are presented, along with Huygens' principle for wave propagation. The content emphasizes the importance of understanding the properties of the environment for predicting wave behavior.
