Electromagnetic Wave Diagram - Electric and Magnetic Field Oscillations #1497603 (License: Personal Use)

This diagram illustrates a plane electromagnetic wave propagating along the horizontal axis, with the electric field (E, blue shaded region) oriented vertically and the magnetic field (B, yellow shaded region) oriented horizontally-both perpendicular to the direction of propagation and to each other. The fields oscillate sinusoidally and remain in phase, demonstrating key principles of Maxwell’s equations and wave optics. Arrows indicate field directions, and the dashed centerline represents the equilibrium position.

Used in educational physics resources, university lecture slides, and science websites to explain EM wave structure, polarization, and wave propagation. Matches user intent for learning foundational electromagnetism concepts.
