39 When radiation of wavelength is incident on a metal surface the stopping potential is 4 8 volts If the same surface is illuminated with radiation of double the wavelength then the stopping potential becomes 1 6 volts Then the thereshold wavelength for the surface is 1 2X 2 4 3 6X 4 8 40 IF 10 of a radioactive material decays in 5 days then the 39 fa fafar va sarfed 12 for at afrost fava 4 8 volts anafaa fan are a farvi fava 1 6 volts tenere is for teens 1 2 2 4X 3 6X 4 8 40 10 20
