55. On the surface of the metal falls radiation with a wavelength of 280 nm. When a retarding voltage photocurrent ceases. If you change the wavelength of the radiation in the 20 nm-retaining capacity had to be increased by 0.34 V. Determine the charge of the electron, Planck´s constant, and considering the speed of light known.
