What is the difference between the threshold frequency and the work function?
one is an energy and one is a frequency work function is the energy required to take an electron ‘out of’ (ionise it) the atom the threshold frequency is the frequency of light that has the same energy (hf) as the work function if light hitting atom has frequency (and therefore energy) greater than the work function, teh left over energy become kinetic energy of the ‘freed’ electron at least i think taht’s wat i remember it
