You can use the momentum #p# of the electron and Planck constant #h# in the general formula of the de Broglie eavelength for the wave of matter associated with the electron:
#lambda=h/p#
Where:
#h=6.63*10^(-34) Js#
#p=mv# the momentum of the eléctron of:
#v=3.85*10^6 m/s#
#m=9.11*10^(-31) kg#

giving: #lambda=1.89*10^(-10) m#
