Derive the expression for p in terms of the Kinetic energy K using the correct relativistic expression. This is always correct but could suffer from numerical inaccuracy. b. Derive the expression for p in the nonrelativistic limit (pc<>mc2). d. In each of the three above cases write an expression for the wavelength taking advantage of our units like MeV/c2 for mass. e. What is the wavelength of a 2 eV photon
