Hello Austin, it is not binding energy it is work function W usually given in eV According to Einstein, hv - hvo 1/2 m v2 ie Kinetic energy Given wavelength 2.73 x 102 nm ie 2.73 x 10-7 m since nano is 10-9 And hvo W 3.73 eV So KE hc/l - 3.73 But hc / l will be in joule. To change it in eV Relativistic kinetic energy is the total energy minus the rest energy.EB binding energy (can be negative or positive) [J] m mass [kg].electron gives up one photon of light energy [m]. DUANE-HUNT RULE.There were exercises where we had to calculate this. I dont know what the significance is. Eventually kinetic energy reaches the maximum at the moment of impact with the Earth, when the stone stops moving.Thus, foods high in nutrient density are foods that have a high amount of nutrients per a given unit of energy. When the kinetic energy of the ejected photoelectron is great enough to enable it to escape the bound state, it interacts with electrons in the bound states of other atomsc mtotal - matomic matomic. (26). The value of the edge energy is used to calculate k(1) as given by the following equation.
