11. Membrane optics employ plastic in place of glass to diffract rather than refract or reflect light. 12. Neutron diffraction can also be employed to give insight into the 3D structure any material that diffracts . 13. The valve diffracts laser light using an array of tiny movable ribbons mounted on a silicon base. 14. In 1916, G . Thomson successfully diffract electrons, providing experimental evidence of wave-particle duality. 15. They then diffract over roof edges into the street, where multipath propagation, absorption and diffraction phenomena dominate. 16. Atoms at the sample surface diffract ( scatter ) the incident electrons due to the wavelike properties of electrons. 17. This is because it diffracts less than blue, which is better at illuminating areas not in direct light. 18. As the beam propagates, it does not diffract , i . e ., does not spread out. 19. The sample surface diffracts electrons, and some of these diffracted electrons reach the detector and form the RHEED pattern. 20. Because gas molecules diffract electrons and affect the quality of the electron gun, RHEED experiments are performed under vacuum.
