Explanation:
Hello,
Photo electric effect theory was borne out the the confusing if light was either a particle or a wave. However Albert Einstein came up with a theory that light was a particle and each particle carry a certain amount of energy referred to as photons.
He used Max Planck's idea and theorized that since light is made up of photon, when each photon comes in contact with the surface of a metal, the energy is transferred to the electron.
E = hv
E = energy of the photons
h = Planck's constant = 6.626×10⁻³⁴Js
v = frequency of the photon in Hz
B. Both mechanical and chemical waethering
