* '''Wave Optics''' — The branch of optics that studies "Interference," "Diffraction," "Polarization," and other phenomena for which the "Ray" approximation is not valid.
* '''Interference''' — When two light waves "Combine" to form a new wave of "Greater" (Constructive) or "Lesser" (Destructive) intensity.
* '''Diffraction''' — The "Bending" of light around the "Edges" of an object or through a "Small slit."
* '''Polarization''' — The "Direction" in which the light wave is "Vibrating" (e.g., 'Up and Down' or 'Left and Right').
* '''Huygens’ Principle''' — The idea that every "Point" on a wavefront is the "Source" of a new "Tiny wave."
* '''Coherence''' — When two light waves have a "Constant Phase" relationship (they 'Wiggle together' in time), necessary for seeing interference patterns.
* '''Thin-Film Interference''' — The "Rainbow colors" seen in "Soap bubbles" or "Oil on water," caused by light reflecting off the "Top and Bottom" layers of the film.
* '''Diffraction Grating''' — An object with "Thousands of tiny slits" that "Splits" light into its "Colors" (The 'CD/DVD' effect).
* '''Young’s Double-Slit Experiment''' — The 1801 experiment that "Proved" light is a wave by showing "Alternating Bright and Dark" bands on a screen.
* '''Resolution Limit''' (Abbe Limit) — The "Fact" that you cannot see an object "Smaller than the wavelength of light" (about 200 nanometers) because of diffraction.
