The longest wavelength radiation that will dislodge electrons from a gold surface is 257 nm. a) Will photoelectrons be ejected from gold by visible light? Explain. (Ans: No) b) Calculate the threshold frequency. (Ans: vo = 1.17 x 10¹5 Hz) c) Calculate the kinetic energy of an electron ejected from a gold surface by 240 nm radiation. (Ans: 5.57 x 10-20 J)
