Who discovered the law of the photoelectric effect?
Keeping this in view, how did Einstein discover the photoelectric effect?
In 1905, Albert Einstein solved this apparent paradox by describing light as composed of discrete quanta, now called photons, rather than continuous waves. By assuming that light actually consisted of discrete energy packets, Einstein wrote an equation for the photoelectric effect that agreed with experimental results.
Also Know, what is photoelectric effect and its law? Laws of Photo-Electricity (a) Photoelectric effect is an instantaneous process. (b) Photoelectric current is directly proportional to the intensity of incident light and is independent of frequency.
Besides, how did Einstein explain the law of photoelectric effect?
Einstein's Explanation Of Photoelectric Effect. The photoelectric effect is a phenomenon where electrons are emitted from the metal surface when the light of sufficient frequency is incident upon. This implies that the kinetic energy of electrons increases with light intensity.
Why was the discovery of the photoelectric effect so important?
Study of the photoelectric effect led to important steps in understanding the quantum nature of light and electrons and influenced the formation of the concept of wave-particle duality. The photoelectric effect is also widely used to investigate electron energy levels in matter.
