What is the photoelectric effect?
Q: What is the photoelectric effect?
A: The photoelectric effect is a phenomenon in physics where electromagnetic radiation is made of particles called photons, and when they hit electrons on a metal surface, the electron can be emitted, forming photoelectrons.
Q: Who discovered the photoelectric effect?
A: Heinrich Rudolf Hertz discovered the photoelectric effect.
Q: Why is the photoelectric effect also called the Hertz Effect?
A: The photoelectric effect is also called the Hertz Effect because it was discovered by Heinrich Rudolf Hertz.
Q: What is the wave-particle duality?
A: The wave-particle duality is a concept developed because of the photoelectric effect, which helped physicists understand the quantum nature of light and electrons.
Q: Who proposed the Laws of Photoelectric Effect?
A: Albert Einstein proposed the Laws of Photoelectric Effect.
Q: What was the contribution of the photoelectric effect to physics?
A: The photoelectric effect has helped physicists understand the quantum nature of light and electrons, developing the concept of wave-particle duality, and contributed to the Laws of Photoelectric Effect proposed by Albert Einstein, who won the Nobel Prize for Physics in 1921.
Q: What are emitted electrons in the photoelectric effect called?
A: The electrons emitted from the metal surface in the photoelectric effect are called photoelectrons.
