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...
On the impossibility of superluminal travel: the warp drive lesson 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:...
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 equation. The wave propagation equation is usually ...
Particle Nature of Light Besides having wave characteristics, light also acts like a particle. The Quantum Concept: Energy can only be gained or lost in a specified amount A Quantum. Equantum = hv h is Plank’s Constant = 6.626 x 10-34 J•s...
The Northern lights are poetry, and they are nature’s light show. They are elementary particle physics, superstition, mythology and fairy tales. 参考答案:北极光充满了诗情画意,使自然之光的展演。它们既蕴含着基本例子物理学的知识,又充满了迷信色彩,关于它还有许多神话传说。

aif a single photon beam is split into two beams, then the particle nature of light requires that each photon is only observed at a single detector, 如果单个的光子横梁被分隔为两个横梁,光的微粒自然要求每光子仅在单个的探测器观察,[translate]...
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 ...
Despite their elusive nature, scientists are keen to detect neutrinos as they can provide valuable information about the processes that produce them. Neutrinos interact with matter so rarely that it takes a very special kind of detector to catch them in the act. These detectors come in a few ...
This method is known for its remarkable efficiency. If a particle is much smaller than both the wavelength of light and the characteristic length of the electromagnetic field, it satisfies the conditions for Rayleigh scattering, and the optical forces can be estimated by treating the particle as ...
