Activity 1: Problem Solving Solve the following problems. 1. Calculate the energy carried by a single photon from a green laser pointer whose wavelength is about 530 nm. 2. A piece of metal has a cutoff wavelength of Acutof f = 450 nm. Consider illuminatmg this piece of metal with two different wavelengths of light: a iii = 500 nm beam and a 212 = 400 nm beam. For each of the two beams, find: a. The maximum kinetic energy of ejected electrons. b. What is their speed? 3. When a 180nm light is used in an experiment with an unknown metal, the measured photocurrent drops to zero at potential 0.80 V. Determine the work function of the metal and its cut-off frequency for the photoelectric effect. 4. A 430mm violet light is incident on a calcium photoelectrode with a work function of 2.71 eV. Find the energy of the incident photons and the maximum kinetic energy of ejected electrons. 5. What is the wavelength of EM radiation that ejects ZOOelf electrons from calcium metal, given that the binding energy is 2.71 eV
