Part 5/10:
Resonant Frequency: Determined by the physical dimensions and shape of the cavity, it defines the frequency at which the cavity efficiently oscillates, similar to a musical instrument's pitch.
Electric and Magnetic Fields: Inside the cavity, electric and magnetic fields oscillate out of phase, exchanging energy periodically. The electric field accelerates or decelerates electrons, while the magnetic field influences their trajectories.
Energy Exchange: The electromagnetic oscillation involves a continuous exchange of energy between electric and magnetic fields, maintaining high-frequency oscillations.
