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...
The question of whether it is possible or not to surpass the speed of light is already centennial. The special theory of relativity took the existence of a... C Barceló,S Finazzi,S Liberati - 《Physics》 被引量: 24发表: 2010年 Radiation Ecologies and the Wars of Light In lieu of an...
Light and Vacuum : The Wave–Particle Nature of the Light and the Quantum Vacuum. Electromagnetic Theory and Quantum Electrodynamics Beyond the Standard Model Man has always been fascinated by light. Since the rise of humanity, light is related to life and darkness to death. This concept seems ...
Nature Podcast | 24 April 2024 How gliding marsupials got their ‘wings’ Researchers find the genetic mutations that allow some marsupials to soar, and an ultra-accurate clock is put through its paces on the high seas. Benjamin Thompson & Elizabeth Gibney Research Highlight | 19 April 202...
Because of the nature of electromagnetic scattering Qsc(λ, r) can approach a value of 2 for non-absorbing particles large compared with the wavelength λ. This is because diffraction occurs around and outside the edges of the particle, causing the effective cross-section to be about 2A for ...
The research, conducted by a team led by Professor Ma Xiaosong, demonstrated conclusively that light can not only be in wave or particle states but also in a quantum superposition of the two. The finding, published in the latest issue of the journal Nature Photonics, helps extend the experime...
Superheavy nuclei represent the limit of nuclear mass and charge; they inhabit the remote corner of the nuclear landscape, whose extent is unknown. The dis... Ćwiok,S.,Heenen,... - 《Nature》 被引量: 111发表: 2005年 Contribution of Base Excision Repair, Nucleotide Excision Repair, and...
of real space. Several features make the nature of the topological mapping clear. The real-space filaments of constant polarisation are mapped to the smooth Hopf circles of fixed polarisation in the optical hypersphere. The images of two typical real space transverse planes (grey grids) are ...
Most of the work is theoretical in nature and uses models to predict aerosol sticking. Often it is assumed that every aerosol that impacts on a wall will stick. The common believe is that they are kept along surfaces by relatively weak van der Waal and electrical forces. However, ...
observed in the particle tunneling through a localized potential: the former predicts a discontinuous transmission coefficient (T) as a function in incident velocity between one (complete penetration) and zero (complete reflection); while in the latter T always changes smoothly with a wave nature. ...
