The average speed of electrons is


v=2Km.v=\sqrt\frac{2K}{m}.

The wavelength is


λ=vf=1f2Km= =11.110921001.6210199.111031=5.39103 m.\lambda=\frac{v}{f}=\frac{1}{f}\sqrt\frac{2K}{m}=\\\space\\ =\frac{1}{1.1\cdot10^9}\sqrt\frac{2\cdot100\cdot1.62\cdot10^{-19}}{9.11\cdot10^{-31}}=5.39\cdot10^{-3}\text{ m}.
