Light of wavelength 380 nm strikes a metal surface, ejecting electrons. They flow through empty space to a second electrode, and it is found that the current stops if the collector is at a voltage 0.85 V, negative with respect to the first metal. Then the wavelength of light is changed to 350 nm. What is the new stopping potential? 5.96 V 1.13 V 0.57 V 3.54 V 2.69 V
