Stopping potential for photoelectrons

In photoelectric experiment when wavelength of light is 642.4 nm falls on metal surface stopping potential of photo electron is 0.48eV. What will be the stoppingpotential when wavelength of light used is 474 nm?

The stopping potential for the photo electrons emitted from a metal surface of work function 1.7 eV is 10.4 V. Identify the energy levels corresponding to the transitions in hydrogen atom which will result in emission of wavelength equal to that of incident radiation for the above photoelectric effect

When monochromatic light of wavelength lambda illuminates a metal surfrce, then stopping potential for photo electric current is 3V_(0) . If wavelength changes to 2lambda then stopping potential becomes V_(0) Threshold wavelength for photo electric emission is:
