The schedule and questions for the final review 2 exam in the physics-astronomy department, focusing on electromagnetism and optics. Students are expected to derive the electric field of an electromagnetic wave, calculate the average energy flux, and determine the wave vector and attenuation length of an absorption process. The document also includes review questions on topics such as brewster's angle, larmor's formula, and rayleigh scattering.
