When ultraviolet light with a wavelength of 354 nm falls on a certain metal surface, the maximum kinetic energy of the emitted photoelectrons is measured to be 1.76 * 10^ 19 J. How much energy, in Joule, does an electron have to gain in order to escape from the metal surface? Exponential format with 3 SF.
