Enter your answer in the provided box. the mathematical equation for studying the photoelectric effect is hν = w + 1 2 meu2 where ν is the frequency of light shining on the metal; w is the energy needed to remove an electron from the metal; and me and u are the mass and speed of the ejected electron, respectively. in an experiment, a student found that a maximum wavelength of 351 nm is needed to just dislodge electrons from a metal surface. calculate the velocity (in m/s) of an ejected electron when the student employed light with a wavelength of 303 nm.
