WebSection Summary. Quantization of orbital energy is caused by the wave nature of matter. Allowed orbits in atoms occur for constructive interference of electrons in the orbit, requiring an integral number of wavelengths to fit in an orbit’s circumference; that is, nλn = 2π rn ( n = 1, 2, 3 …), where λn is the electron’s de Broglie ...

One of the most famous experiments in physics is the double slit experiment. It demonstrates, with unparalleled strangeness, that little particles of matter have something of a wave about them, and suggests that the very act of observing a particle has a dramatic effect on its behaviour.
WebA modified oscilloscope is used to perform an electron interference experiment. Electrons are incident on a pair of narrow slits 0.060 0 μ m apart. The bright bands in the interference pattern are separated by 0.400 mm on a screen 20.0 cm from the slits. Determine the potential difference through which the electrons were accelerated to give ... Electron diffraction refers to changes in the direction of electron beams due to interactions with atoms. The resulting map of the directions of the electrons after they have interacted is called a diffraction pattern. It is similar to x-ray and neutron diffraction. Electron diffraction occurs due to elastic scattering, when there is no change i…
