Homework Statement
Compare a 2.2eV photon with a 2.2 eV electron in terms of energy, rest mass, speed, wavelength, and momentum
The attempt at a solution
So...
E = (2.2eV) x (1.60 x 10-19 J/eV) = 3.52 x 10-19 J
Wouldn't 3.52 x 10-19 J be the energy for both the photon and electron? If so, wouldn't that make mass, speed, wavelength, and momentum equal for both particles?
