i. Calculate the maximum wavelength max of electromagnetic radiation that could eject electrons from the surface of lead with a work function of 6.80x10^-19 J. ii. If the max speed of the emitted electrons is 3.65x10^6 m/s, what wavelength of electromagnetic radiation struck the surface and caused ejection of the photoelectrons? Use an electron mass of 9.11x10^-31 kg if needed
