At what speed must an electron travel to have a wave- length of 10.0 pm?
Use De Broglie's wave equation to calculate the wavelength of an electron moving at the speed of light (299,800,000 m/s). What is the wavelength in PICOMETERS? Remember that there are 1012 pm in 1m. Wavelength must be converted to meters and frequency to Hertz before plugging in to the equation.
