Hace 3 días · The Michelson–Morley experiment was an attempt to measure the motion of the Earth relative to the luminiferous aether, a supposed medium permeating space that was thought to be the carrier of light waves.The experiment was performed between April and July 1887 by American physicists Albert A. Michelson and Edward W. Morley at what is now Case Western Reserve University in Cleveland, Ohio ...
Hace 1 día · Matter waves are a central part of the theory of quantum mechanics, being half of wave–particle duality.At all scales where measurements have been practical, matter exhibits wave-like behavior.For example, a beam of electrons can be diffracted just like a beam of light or a water wave.. The concept that matter behaves like a wave was proposed by French physicist Louis de Broglie (/ d ə ˈ b ...
Hace 1 día · In this study, we present evidence of the nonreciprocal diffraction of surface acoustic wave (SAW) utilizing a magnetoelastic grating on a SAW device. Asymmetric diffraction intensities were observed when the ferromagnetic resonance was acoustically excited. Based on a theoretical model, we attribute the microscopic origin of this phenomenon to ...
Hace 6 días · The diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small opening. Effects similar to this occur when light travels through a medium with a varying refractive index. Diffraction can occur with different types of waves.
Hace 5 días · Diffraction Grating. Procedure for real lab. The preliminary adjustments of the spectrometer are made. The grating is set for normal incidence. The slit is illuminated by mercury vapour vamp. The telescope is brought in a line with the collimator and the direct image of the slit is made to coincide with the vertical cross wire.

Hace 2 días · The narrowest and sharpest diffraction peak in Ni-BHT further exhibits its high crystallinity. Figure 2b displays a pronounced ring-shaped (001) scattering phenomenon in the 2D GIWAXS pattern of Ni-BHT, relating to the π stacking direction.
