A photon has an energy equal to the kinetic energy of an electron with speed, u, which may be close to the speed of light, c.
a) Calculate the ratio of the wavelength of the photon to the wavelength of the electron (Use: u, c, and gamma as neccessary)
b) Evaluate the ratio for the particle speed u=0.924c.
d) Evaluate the ratio for the particle speed u=0.0021c.
e) What value does the ratio of the wavelengths approach at high particle speeds?
