A flat aluminum electrode is illuminated by ultraviolet radiation with a wavelength of L = 8.3 • 10-8 m. What is the maximum distance that a photoelectron can move from the surface of the electrode if there is a retarding uniform electric field of intensity E = 750 V/m outside the electrode? The red boundary of the photoelectric effect for aluminum corresponds to the wavelength L0=33.2•10-8.
