A silicon (Φ = 7.77 × 10-19 J) surface is irradiated with UV radiation with a wavelength of 225 nm. Assume an electron was a mass of 9.11 x 10-31 kg. What is the frequency of the incident radiation? What is the kinetic energy of the emitted electrons? What is the speed of the emitted electrons? What is the wavelength of the emitted electrons?
