In a photoelectric effect experiment, electrons are ejected from a titanium surface (work function, 3 ev) following irradiation with uv light. the energy of the incident uv light is 7.2 x 10-19 j.
(a) calculate the wavelength of the ejected electrons.
(b) calculate the wavelength of the incident uv light.
(c) would an iron surface (ф-4.7 ev require a longer or shorter wavelength of light to eject electrons with the same wavelength calculated in part (a)? briefly explain.
