Light from a laser incident on a platinum plate with a work function of 6.35 eV has half the wavelength obtained in the previous question. It is observed to drive an electron current of 0.15 A. What will be the current, in A, if the laser power is doubled while the wavelength remains half that obtained in the previous question? Answer:

Question

Using the answers provided in the first figure in the fields, please help solve the second question in the figure

In a photoelectric effect experiment, the stopping potential is observed to drop from 6 V to 2 V when the wavelength of incident light is doubled. The work function of the irradiated metal is W= 2 eV The frequency of the light in the original setup is therefore f = 1.93e15 Hz You should type in large numbers using exponential notation, e.g. enter 1.6 x 10" as 1.бе11
