A photon and an electron have the same de-broglie wavelength.which one has greater total energy?

Dear Student,

electron.... bcoz wavelength inversely proportional to sq. root of product of mass and KE..... since for the same wavelength it is necessary for that the product of both for electron and proton are same..... but mass of proton is greater so its energy is is less.... viceversa...
