Light with a wavelength of 300 nm is incident on the cathode of a photoelectric tube. It is observed that the maximum kinetic energy of the electrons ejected from the metal is 0.5 eV. Then, you shine light with a wavelength of 250 nm. What is the de Broglie wavelength of the electrons ejected from the metal by the second light source?
