When a metal surface is illuminated by a monochromatic light of wave-length lambda , then the potential difference required to stop the ejection of electrons is 3V . When the same surface is illuminated by the light of wavelength 2lambda , then the potential difference required to stop the ejection of electrons is V . Then for photoelectric effect, the threshold wavelength for the metal surface will be
