Covers the nature of electromagnetic waves, including plane waves and photons, their wavelength, period, and dispersion relationship, and the electromagnetic spectrum.
Explores charge density, electric field, Coulomb's law, and electric potential relationships, including forces between charges and the dominance of gravitational and electrostatic forces.
Introduces electrostatics, focusing on Coulomb's force, electric field representation, superposition principle, and visualization of electric field vectors using field lines.
