While you were calculating, the aliens did make a move. They were trying to hit you with electrons that come out through photoelectric effect. They were good--they made sure that the light beam that they use was above the cutoff frequency so that electrons do indeed come out and hit you. If the work function of the metal that aliens are using is 2.4 eV, what is a cutoff frequency of photoelectric effect? O 5.8 x 1014 Hz O 5.8 x 1016 Hz x O 3.6 x 1033 Hz O 3.6 x 1015 Hz
