You did not give the correct unit.
The correct answer is
Consider the following graph showing the results of a photoelectric effect experiment using Iight with a wavelength of 200 nm. Each horizontal box is \( 0.50 \mathrm{~V} \) and each vertical box is \( 1.0 \mathrm{~mA} \). What is the power of the light source used in this experiment? Assume perfect efficiency. You did not give the correct unit. The correct answer is: \( 24.8 \mathrm{~mW} \) What is the threshold wavelength in this experiment? Answer: Wh ot is the work function of the electrode used in this experiment? You did not give the correct unit. The correct answer is: \( 4.2 \mathrm{eV} \)
