Question

next four questions pertain to the situation described below. he electron kinetic energy versus photon frequency due to the photoelectric effect of three different ma Assignment Set Tool shown MIax material A material C 4f 3) Which material requires the less energetic photons to have electrons ejected? a. Material A b. Material B c. Material C 4) Briefly explain your answer to the previous question. 5) If light of frequency f-3 f, is shone on the three materials, which of the following will be true? a. All materials will have electrons ejected b. None of the materials will have electrons ejected c. Only materials A and B will have electrons ejected d. Only material C will have electrons ejected 6) Briefly explain your answer to the previous question.

Explanation / Answer

E( kinetic energy) = hf - work function

material A because electrons have started ejecting at a lower frequency

b) only material A and B will have electrons ejected as the incident frequency is higher than frequency required to eject electrons
