The Photo-Electric Effect is the phenomenon where certain materials emit electrons when exposed to light. This discovery was significant as it provided evidence for the particle nature of light and laid the foundation for the development of quantum mechanics.
Einstein was awarded the Nobel Prize in Physics in 1921 for his explanation of the Photo-Electric Effect.
Einstein's theory proposed that light behaves as both a wave and a particle, contrary to the classical view that it only behaved as a wave. This challenged long-held beliefs about the nature of light and led to the development of quantum mechanics.
No, the Photo-Electric Effect was first observed by Heinrich Hertz in 1887. However, Einstein's explanation of the phenomenon and his contributions to the understanding of light earned him the Nobel Prize.
The Nobel Prize brought Einstein international recognition and solidified his reputation as a groundbreaking scientist. It also allowed him to continue his research and work on his theory of relativity, which would go on to have a significant impact on modern physics.
