WebIn 1905 Albert Einstein was able to provide an explanation of the photoelectric effect. He proposed that light acts like a particle having energy equal to nf, where n is Planck's constant and f is the frequency of the incident light. These particles of light, called photons or quanta collide with and transfer energy to the electrons in the metal. WebIn the photoelectric effect, if the intensity of a light is shone on metal increases, what will happen? A.) ejected electrons will be faster B.)ejected electrons will be slower C.)there would be more electrons ejected D.)there would be fewer electrons ejected E.)no change .

The Photoelectric Effect - Definition, Laws, Applications, …
Webphotoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined … The photoelectric effect was first introduced by Wilhelm Ludwig Franz Hallwachs in the year 1887 and the experimental verification was done by Heinrich Rudolf Hertz. They observed that when a surface is exposed to electromagnetic radiation at a higher threshold frequency, the radiation is absorbed and the … See more The photoelectric effect cannot be explained by considering light as a wave. However, this phenomenon can be explained by the particle nature of light, in which light can be … See more The photoelectric effect is the process that involves the ejection or release of electrons from the surface of materials (generally a metal) when light falls on them. The photoelectric effect is an important concept … See more According to Einstein’s explanation of the photoelectric effect: The energy of photon = energy needed to remove an electron + kinetic energy of the … See more WebWhen monochromatic light of wavelength ' λ ' is incident on a metallic surface, the stopping potential for photoelectric current is ' 3 V 0 '.
