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 3 eV. You may assume h=4x10^-15 eV s and c=3x10^8 m/s. a) If a photon of 350 nm wavelength interacts with the plate, an electron will be released T/F? Justify your ans on your show your work sheet?
