When radiation of wavelength A is incident on a photo

When radiation of wavelength A is incident on a photo sensitive metallic surface the stopping potential is 3 6 volt If the same surface is illuminated with radiation of double wavelength then the stopping potential becomes 1 2 V Then the threshold wavelength of the metal surface is O 4 O 2A OX O 3
