What is the velocity (in m/s) of an electron that has a wavelength of 3.13 x 105 pm? (Mass of an electron = 9.11 x 10-31 kg).
The faster an electron is moving, the _________ its kinetic energy, and the __________ its wavelength.
Consider an atom traveling at 1% the speed of light. The de Broglie wavelength is found to be 7.1316 x 10-39 m. Which element is this?
