Put the following forms of electromagnetic radiation in order of increasing energy: X-ray Lowest Energy Clear All Visible Second Highest Energy Infrared Highest Energy
The work function (binding energy) is the energy that must be supplied to cause the release of an electron from a photoelectric material. The corresponding photon frequency is the threshold frequency. The higher the energy of the incident light, the more kinetic energy the electrons have in moving away from the surface. The work function for cesium (used in IR lamps) is equivalent to 202.6 kJ/mol photons. Use this information to calculate the energy, wavelength, and velocity of ejected electrons. What is the kinetic energy, in Joules, of each ejected electron when light of 250.0 nm strikes the metal surface? 4
