the phenomenon is only investigated in metals as they require lower energy from the radiation. The photoelectric effect was first discovered by Heinrich Hertz in 1887 and was explained by Albert Einstein in 1905. Einstein’s model quantized light as photons‚ each with energy E=hν where h is the Planck’s constant and ν is the frequency. Einstein also introduced the work function ϕ of a material‚ defined as the minimum amount of energy needed in order to liberate an electron
