Can an electron with a de Broglie wavelength of 2 μm pass through a slit that is 1 μm wide? Select the correct answer and explanation. Can an electron with a de Broglie wavelength of 2 pass through a slit that is 1 wide? Select the correct answer and explanation. Yes. If the electron was a classic particle it would be impossible, but electron can pass through the slit due to quantum tunneling. Yes. Electron wavelength is only a measure of how rapidly its amplitude varies as measured along its direction of motion and has nothing to do with passing through the slit. No. Electron can only pass through a slit that is wider than the electron wavelength. It is impossible to say because electron can only pass through a slit that is wider than the half of the electron wavelength. More precise values of the wavelength and the slit width are necessary.
