Description
Hi, I am doing photoelectric effect experiment. I want you to write me a report or some kind of a research about the history of photoelectric effectexperiment. Then, I want you to write the theory, Furthermore, i want you to wrote the formulas we need to find out what is photoelectric effect is trying to achieve. Make it looks like a physics report please. I am telling you that because I do not want to have argument after you submit the results.

hello, find the report. in case of any issues feel free to raise. thanks
PHOTOELECTRIC EFFECT
Objectives
To determine Photoelectric effect theory
To measure different voltages associated with different wavelengths of light
To determine the value of Plank’s constant.
Introduction
In the year 1887, Hertz discovered that when a light of sufficient frequency is illuminated on a
metallic surface, electricity may be emitted. In 1900 Lenard identified positively the liberated
particles like electrons and their energies. He studied the fraction of the number and energy of
electrons as a function of the wavelength of the incident light and its intensity. The results from
this study were not able to be proved using the wave theory of light.
The phenomenon was not explained until Einstein with the help of Planck’s idea of radiation
comes in small quanta experimented. According to Einstein, the energy of the ejected electrons is
proportional to the energy of the incident light with a constant called work function. As the
intensity of light increases, the energy of the emitted electrons would increase. The photoelectric
effect is the emission of electrons from the surface of the metal when ...
