These are refraction, diffraction, and reflection. What is the difference between diffraction and refraction of light? Diffraction is the bending of light around an obstacle or through a gap. Refraction is the bending of light as it moves from one medium to another. In refraction, the speed ...
The refraction/ diffraction mixed heat difference abstraction infrared optical system of dual optical elements can obtain the imaging quality close to diffraction limit in wide visual field and very good chromatic aberration correction in wide temperature range. The defocus quantity of the system is ...
They differ from prismatic spectra, since in them the colors are uniformly distributed in their true order and extent according to their difference in wave-length; while in the latter the less refrangible (red) rays are crowded together, and the more refrangible (blue, violet) are dispersed...

The current is shown to significantly affect the steady drift force and runup predictions. Comparisons of the computed wave forces are made with a previous numerical solution involving a semi- immersed sphere in deep water, and indicate good agreement. 展开 关键词: engineering not included in ...
XRD is a scientific method of determining the precise positions or arrangements of atoms in a crystal or amorphous material where beams of X-rays strike a crystal and causes the beam of light to diffract into many specific directions.
This makes it so that the rays from atoms in the same plane have zero path distance difference between them, and thereby also constructively interfere. Thereby, with the Bragg condition, the rays from all of the atoms in the crystal constructively interfere, (as viewed in the far field). ...
