yes it does. by the de broglie relationship h/mv= wavelength.
where h = plank's constant and m= electron's mass or it might be any object that posses mass and v= velocity. everything has to be in SI units.

The wavelength of an electron is given by h/p where h is Planck's constant and p is the momentum of the electron. As the velocity approaches the speed of light, the momentum goes to infinity, so the wavelength goes to zero. The previous poster used p=mv, which is the classical expression for the momentum. The correct expression for speeds approaching that of light is
p=mv/sqrt(1-(v/c)^2 ).

Yes and no. If you are at rest relative to the electron then its wavelength does indeed contract; however, if you moving along with the electron then nothing changes.
