Reflected light is interpreted as a “1” and unreflected light is interpreted as a “0.” The resulting digital signal is converted into an analog signal, and the analog signal is fed into an amplifier that powers a device such as a pair of headphones.

Laser light is produced by population inversion and subsequent de-excitation of electrons in a material (solid, liquid, or gas). When a photon of energy triggers an electron in a metastable state to drop in energy emitting an additional photon, it provokes stimulated emission.

An interference pattern is obtained by the superposition of light from two slits. When light passes through narrow slits, the slits act as sources of coherent waves and light spreads out as semicircular waves. Pure constructive interference occurs where the waves are crest to crest or trough to trough. Pure destructive interference occurs where they are crest to trough.
