👉 A pantelephone is a type of light source that emits light in the form of waves. It is named after its inventor, the Greek physicist and astronomer Aristarchus of Samos (c. 325-270 BC). The name "pantelephone" comes from the Greek word "panethos," which means "light wave." These light waves are emitted by the pantelephone and reflect off objects, creating a wide range of colors.
