By 1000, the Pythagorean model of light had been abandoned, and a ray model, containing the basic conceptual elements of what is now known as geometrical optics, had emerged. In particular, Ibn al-Haytham (Latinized as Alhazen), in Kitab al-manazir (c. 1038; “Optics”), correctly ...

X-Ray Astronomy M.F.Corcoran, inEncyclopedia of Physical Science and Technology (Third Edition), 2003 IOverview The spectrum ofelectromagnetic radiationis divided into about seven discrete regions based on wavelength or energy. The X-ray energy band comprises radiation with energy in the range a ...

Braun and Boles (1982) recommend supporting the PLM method by at least another method, such as the scanning electron microscopy combined with the energy dispersive X-ray spectrometry (SEM–EDS) and the XRD method.

We study the weighted light ray transform L of integrating functions on a Lorentzian manifold over lightlike geodesics. We analyze L as a Fourier Integral Operator and show that if there are no conjugate points, one can recover the spacelike singularities of a function f from its the weighted...
Fast and furious X-ray free-electron lasers Global proliferation of free-electron laser X-ray sources has improved accessibility. Now the race is on for high repetition rates, attosecond pulses, and full coherence. News & Views | 08 July 2024 The X-ray science frontier is ultra-short and...
The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a variety of real-world phenomena; refraction principles are combined with ray diagrams to explain why
