Light Wave Reflection and Phase Inversion Diagram #1434988 (License: Personal Use)

This schematic illustrates two incident light waves striking a boundary: the upper wave reflects without phase change, while the lower wave undergoes a 180-degree phase inversion due to reflection from a higher-index medium. The blue sinusoidal curves represent electric field oscillations, with orange lines indicating equilibrium positions; the black arrows denote direction of propagation.

Used in physics education, optics tutorials, and engineering resources to explain Fresnel equations, anti-reflective coatings, and interference phenomena like Newton’s rings or soap film colors. Matches user intent for learning wave behavior at interfaces.
