What evidence supports the notion that light has wave properties? What evidence supports the view that light has particle properties?. What is the evidence that light is energy? What evidence can you cite for the wave nature of light and for the particle nature of light? What type of expe...
(5) The dimming region behind the wavefront stopped to expand when the wavefront started to become diffuse. (6) The profiles of the wavefront exhibited a dispersive nature, and the magnetosonic Mach number of the EUV wave derived from the highest intensity jump is about 1.4. In addition, ...
No energy is detected in the dark/null zones of wave interference. Because energy appears to be absent, the exchange of momentum through the null zone must redirect/repel light waves into bright zones. Our Zero-Slit Experiment (ZSX) provides diffraction-free interference in air between two ...
(Fig.1a). This implies a density deficit of around 27% relative to liquid Fe, which is almost three times that inferred for Earth’s liquid outer core23,24,25and suggests significant light-element enrichment in Mars’s core2,4,5. By contrast, the P-wave velocity of liquid Fe at Mars...

Since the rise of humanity, light is related to life and darkness to death. This concept seems to have intrinsic roots in the human mind whatever the tribe or nation, on any continent and during a... M Constantin 被引量: 0发表: 2017年 Light and Vacuum: The Wave-Particle Nature of ...
One may ask whether the second Born approximation also fails for exciton-exciton scattering in two-dimensional structures and how this breakdown may be experimentally detected. In this contribution, we address this question within a microscopic theory of frequency-degenerate four-wave-mixing signals ...
Large dunefield flattenings were observed and interpreted as the result of wave-cut erosion by the paleolake. Similarities were noticed between the landforms observed along the paleoshoreline of Megalake Chad and that of the former Aral Sea. This finding has significant consequences for ...
(2.33 eV). The angle data shown in Fig.1eis fitted by a sine function,y = y0 + A*sin (B*α + φ), whereyis the intensity of SHG,y0,A,Bare constants,αis the angle of rotation of the half-wave plate, andφis a fitting parameter defining the relative ...
