11. The uncertainty in energy involved in the uncertainty principle is due to the wave nature of particles. 12. At the time of Arago's discovery, Poisson's spot gave convincing evidence for the contested wave nature of light. 13. The square-wave nature of the power flow allows lamp life to be extended by as much as 20 %. 14. At the particle level, heavier things are smaller and lighter things are bigger due to the wave nature of things. 15. Such features again emphasize that the shapes of atomic orbitals are a direct consequence of the wave nature of electrons. 16. It was particularly telling that diffraction in a crystal lattice could only be explained with reference to its wave nature . 17. The wave nature of light limits the size of the spot to which light can be focused due to the diffraction limit. 18. He succeeded in observing the predicted spot, which convinced most scientists of the wave nature of light and gave Fresnel the win. 19. There can be little doubt about the wave nature of light and all other electromagnetic radiations . What did Max Planck discover? 20. The wave nature of light becomes important at small scales such as those in ASPs, meaning a pure-moire model of ASP function is insufficient.
