WebEinstein was able to use Planck's quantization hypothesis to explain the photoelectric effect. As indicated in Figure 6.2.2 a minimum energy of 2.0 eV is required to eject a photon off of potassium, and so red light would not work, while green and purple would. Figure 6.2.2: Potassium requires 2.0eV to eject an electron, and a photon of red ... WebApr 8, 2024 · The formula of Wavenumber in spectroscopy and chemistry fields is given as v̅ = 1/λ = ω/2πc = v/c. Where v̅ is the spectroscopy wavenumber.λ is the wavelength sometimes called a spectroscopic wavenumber which is equal to the spatial frequency.
