Drag the slide bar of wavelength all the way to the right at 850 nm. Set the target to be Sodium and the intensity of light to be 20%. 2. Check the box of "Current vs light intensity" and the box of "Electron energy vs light frequency" 3. Slowly drag the slide bar of wavelength to the left until electrons are released. Keep slowly moving the bar all the way to the left and observe the change of electron speed. Answer Post Lab Questions Part I, #1. The curve of electron energy vs. frequency was automatically generated. 4. Slowly drag the slide bar of intensity all the way to right and observe the change of the amount of electrons. Answer Post Lab Questions Part I, #2. The curve of current vs. light intensity was automatically generated. 5. Take a screen shot of the curve of electron energy vs. frequency and the curve of current vs. light intensity. You will upload the screen shot to Canvas when you take the online quiz.
