(e) 3.79 MeV 4. It is found that the potential required to stop photo-emission from a certain metal surface for light of 400 nm wavelength is 1.1 Volts. What is the momentum of the emitted electrons in the absence of the stopping potential? Hint: Treat the electrons non-relativistically, so KE=p²/2m, with m. 9.11 x 10-31 kg. (a) 6.54 x 10-20 N-6 (b) 1.32 x 10-25 Nis (e) 3.14 x 10-25 N-s (d) 2.00 x 10-24 Na (e) 5.66 x 10-25 N-s
