Summary Light behaves like a wave or a particle. Various terms are used to describe the luminous phenomena found in nature: light, electromagnetic waves or photons. A mathematical description of light in wave optics theory requires that the associated wave function be a solution to the propagation...
Wave-like behavior of microscopic particles, e.g. interference, and, in general, the particle-wave duality is “the mystery”, as stated by Feynman1, “which is impossible, absolutely impossible, to explain in any classical way, and which has in it the heart of quantum mechanics”. The do...
The concept of 'wave-particle duality was created by Louis-Victor de Broglie in 1923 as part of his doctoral dissertation and used to understand the wave nature of matter. Learn more about its relevance to science, learn to calculate de-Broglie wavelength, and recall an electron microscope func...
This paper reports on a study of student understanding of the wave nature of matter in the context of the pattern produced by the diffraction and interference of particles. Students in first-year, second-year, and third-year physics courses were asked to predict and explain how a single change...
Waves and particles are considered two fundamental attributes of light and matter. Based on optical phenomena, such as interference, diffraction, and scattering, light exhibits wave-like behavior, whereas according to other phenomena, such as light traveling in straight lines and the photoelectric effec...
CHAPTER 24 THE WAVE NATURE OF LIGHT Huygen's principle, which states that all points along a wave front act as if they were point sources. Thus, when a wave comes against a barrier with a small opening, all but one of the effective point sources are blocked, and the light coming throug...

Since a lower limit on q is one electronic charge, this value yields a lower limit to the size of spoke particles of about 10−2 µm. The criteria for electrostatically ejecting small particles from larger parent bodies indicate an upper limit of about 10³ m for the parent bodies. ...
It has also been found that the survival potential of the SARS-CoV-2 virus is dependent on different environmental conditions and pollution. Potentially important pathways include aerosol and fecal matter. Particulate matter may also be a carrier for SARS-CoV-2. Since microscopic particles can be ...
