26 de abr. de 2024 · Diffraction, the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very small moving particles such as atoms, neutrons, and electrons, which show wavelike properties.

Hace 3 días · Electron diffraction is a generic term for phenomena associated with changes in the direction of electron beams due to elastic interactions with atoms. [a] It occurs due to elastic scattering, when there is no change in the energy of the electrons. [1] : .
Hace 4 días · In optics and in wave propagation in general, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency; sometimes the term chromatic dispersion is used for specificity to optics in particular.
Hace 3 días · A powder X-ray diffractometer in motion. X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions.
Hace 3 días · Diffraction occurs when light waves pass through a gap or travel parallel to a surface and reach the end of the surface. The angle of diffraction of light waves is maximum for a gap with a width equal to the wavelength of the light waves.
Hace 3 días · Spectrometer, diffraction grating element and mercury vapor lamp. Theory: When a wave train strikes an obstacle, the light ray will bend at the corners and edges of it, which causes the spreading of light waves into the geometrical shadow of the obstacle. This phenomenon is termed as diffraction. Single slit diffraction:
14 de may. de 2024 · wave, propagation of disturbances from place to place in a regular and organized way. Most familiar are surface waves that travel on water, but sound, light, and the motion of subatomic particles all exhibit wavelike properties.
