The minimum energy needed to eject an electron from a potassium atom is 6.96 × 10−19 J. What is the maximum wavelength of light, in nanometers, that will show a photoelectric effect with potassium?
The minimum energy needed to eject an electron from an atom is called its ionization energy I. In atomic physics, I is usually measured in electron-Volts (eV), with 1 eV being the energy needed to move a charge of 1 e across an electrostatic potential difference of 1 V, 1 eV = 1.602 x 10-19 CX1V -1.602 x 10-19 J. For the hydrogen atom | = 13.60 eV. If a photon ejects an electron with kinetic energy 5.0 eV from...
17. It takes 254 kJ/mol to eject electrons from a certain metal surface. What is the longest wavelength of light (nm) that can be used to eject electrons from the surface of this metal via the photoelectric effect 18. Why does this question ask you about the 'longest wavelength of radiation, rather than the 'shortest'? 19. When radiation of wavelength 2.45 x 10'm falls on a metal surface, the maximum kinetic energy of the emitted electrons is found to be...
