Flashcards

Wave-Particle Duality of Light

The ability of light to act as both a wave and a particle.

Quantum Generator (Laser)

A device that generates light through quantum processes, often using stimulated emission.

Interference of Light

The phenomenon where two or more waves of light interact and create patterns of constructive and destructive interference.

Holography

A photographic technique that records the interference pattern of light waves, creating a 3D image.
