In order to explain the results of a photoelectric effect experiment, quantum physics suggests that:(select all that apply)Question 3Answera.light energy is quantised (in the form of photons)b.electron energies are quantised into levelsc.electrons store the energy from several photons to build up and excite over time.d.electrons can interact with photons only on an all or nothing basise.electrons can absorb any energyf.electrons can only be ejected from a metal with an excess negative chargeCheckQuestion 3

Metal A has a higher work function than metal B.The lowest frequency of light that will cause electrons to be emitted from metal B is fBWhich of the following is true:Select one:a.light of any frequency will cause photoelectrons to be emitted from metal A, but only above a threshold intensity determined by the work functionb.light of any frequency will cause photoelectrons to be emitted from metal A, but the lower the frequency, the longer it takes for the photoelectrons to start being emittedc.light of frequency fB will cause photoelectrons to be emitted, but the maximum current will be less.d.light of frequency fB will emit photoelectrons from metal A if the biasing voltage is increased enoughe.light of frequency higher than fB is needed emit photoelectrons from metal A, regardless of its intensity
