momentum = m*v = ?

de Broglie wavelength = h/{momentum) = ?

You do the numbers. You will need to look up the speed of light (c), electrom mass (m), and Planck's constant (h).

I am using nonrelativistic (before Einstein) formulas. The correct formulas will differ by a factor of sqrt [1 - (v/c)^2]= 0.995
