Beryllium has a work function of 5.0 eV. Calculate the minimum frequency of light that would eject electrons in the photoelectric effect experiment. If light of frequency 8*1015 Hz was used, what would be the maximum kinetic energy of the ejected electrons? ????max = hf - Wo I know how to calculate the maximum kinetic energy for this question using the formula above but what formula would be used to calculate the minimum frequency needed to eject the electrons? I...

This question has multiple parts. Work all the parts to get the most points. The energy of a photon needed to cause ejection of an electron from a photoemissive metal is expressed as the sum of the binding energy of the electron plus the kinetic energy of the emitted electron. When photons of 4.40x107m light strike a calcium metal surface, electrons are ejected with a kinetic energy of 1.75x10-20 J. a Calculate the binding energy of the calcium electrons. b...
