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...

This is a demonstration of the_____, primarily studied by Einstein which demonstrated the ___ nature of light.
What is the binding energy in eV of electrons in ruthenium, if the longest-wavelength photon that can eject electrons is 264 nm?
In the photo-electric effect, the minimum energy required for a single photon to be able to free an electron is called the work function, which we will denote as phi. If phi = 2.28 eV for a particular target, what is the maximum wavelength that a photon can have while still being able to free an electron from the target? What would be the kinetic energy of the electron that is freed by the photon in part a)? If we...
