- In an experiment to study the photo-electric effect, light of wavelength 400 nm shining on a metallic surface causes electrons to be emitted. The maximum kinetic energy of the electrons is 1.05 eV (electron volts). Another light source of wavelength 200 nm is then tried, and the emitted electrons have a maximum kinetic energy of 4.20 eV. Using this information: a) determine the value of Planck's constant. b) determine the work function of the metal.arrow_forwardA nickel crystal’s work function is measured to be 5.22 eV at 25°C. As the temperature increases by 300°C, the work function drops by 50 meV. By how much does this shift the threshold wavelength for photoelectric emission?arrow_forward
