Consider maxwell's equations and the prediction of electromagnetic waves. a dentify the equations maxewell used to derive the existence of electromagnetic waves and explain which termls) i those equations was(were) not used in the derivation. b) show the details of maxwell's derivation of the generalized form of ampere's law 2) consider the process of refraction. a) what happens to the frequency and the wavelength of a wave as it enters a material of a different index of refraction? b) for a converging glass lens, what is the relationship between the focal lengths for blue light and red light? explain your answer. 3) what was the photoelectric effect and how did einstein explain the phenomenon? 4) describe the thought experimen the speed of light to be the same, no matter t and reasoning that led einstein to the conclusion that all observers must meas
