What is the scientific phenomenon Richardson is known for?
Radioactivity
Thermionic Emission
Quantum Mechanics
Relativity
Answer
Thermionic emission, wherein the Richardson effect is observed, occurs when heat energy is used to free electrons from a metal's surface, creating an electric current in a vacuum. This phenomenon is named after English physicist Owen Richardson, who conducted pioneering research in the early 20th century and formulated a mathematical equation to quantify the relationship between temperature and the rate of emitted electrons.
