Calculate the maximum wavelength, Amax, of electromagnetic radiation that could eject electrons from the surface of aluminum, which has a work function of 6.50 x 10^-19 J. If the maximum speed of the emitted photoelectrons is 2.30 x 10^6 m/s, what wavelength of electromagnetic radiation struck the surface and caused the ejection of the photoelectrons?
