Which important principle did Lenard experimentally realize?
Relativity principle
Quantum principle
Photoelectric effect
Gravity principle
Answer
The photoelectric effect is a phenomenon in which electrically charged particles are emitted from the surface of a material when it is exposed to light. It is the basis of many modern technologies, such as solar cells and photodiodes. Lenard's experiments on the photoelectric effect helped to establish the wave-particle duality of light and laid the foundation for quantum mechanics.
