when photons of energy 4.25ev strike at surface of a metal A, the ejected e- have maximum kinetic energy, Ta & de broglie wavelength lemda athek maxofe- emitted from other metal B by photons of energy 4.20ev is Tb = Ta - 1.50ev. If de broglie wavelength of these e- is lemda B = 2*lemda Athen which is not correct?A; work function of A is 2.25evB; work function of B is 3.70evC; Ta=2evD; Tb=2.75ev
