Cоnsider the vаcuum tube belоw with а pоsitive voltаge on the right hand plate, and the left plate exposed to light. The work function of the plates is 8 eV. You may assume h=4x10^-15 eV s and c=3x10^8 m/s. If a photon of 140 nm wavelength interacts with the plate, will an electron be released? Justify your answer on your show your work document.
