In this wave problem the only given is velocity of an electron moving at 3.66 x 10⁶m/s. Electron particles had been known to have a mass equivalent to m=9.10938 x 10⁻³¹ Kilograms.We also have to consider the Plank's constant which have a value of h=6.62607 x 10⁻³⁴ m² kg/s. You must insert all the value given above to this given equation "λ=h/mv". λ = greek letter lambda for wavelength. The unit should be in meters.
