1. Choose a metal and choose a wavelength that ejects electrons at a reasonable speed. Turn the light intensity up and down. Make note of the number of electrons ejected. Why does the number change? Explain, with reference to quantum theory. 2. Using this same wavelength and 100% intensity, change the flow
