Description: Defines a cavity resonator and shows the step-by-step development of a cylindrical cavity resonator. Explains how the physical dimensions and shape of the cavity determine the primary resonant frequency. Explains that energy in a cavity is comprised of electric fields and magnetic fields, and how to distinguish between the two. Using a model of a cavity resonator, demonstrates capacitive and inductive tuning of a cavity resonator. (Kinescope)
