Diffraction occurs when a wave encounters an obstacle or aperture that is comparable in size to the wavelength of the wave. The diffraction effect is most pronounced when the size of the obstacle or aperture is on the same order of magnitude as the wavelength of the wave.
Conditions of diffraction refer to the requirements that must be met in order for diffraction to occur, such as having a wave encounter an obstacle or aperture that is comparable in size to the wavelength of the wave. Additionally, the wave must be coherent and the path difference between different parts of the wave should be within half a wavelength to observe constructive interference.
Diffraction. It occurs when waves encounter an obstacle or aperture and bend around it, spreading out into the region behind the barrier.
Diffraction is the bending of waves around obstacles and the spreading of waves as they pass through apertures. The amount of diffraction depends on the wavelength of the wave: shorter wavelengths produce less diffraction, while longer wavelengths produce more pronounced diffraction effects.
Another term for Fraunhofer diffraction is far-field diffraction. This type of diffraction occurs when the distance between the diffracting object and the screen observing the diffraction pattern is much greater than the dimensions of the diffracting object.
In a diffraction grating experiment, the relationship between the diffraction angle and the wavelength of light is described by the equation: d(sin) m. Here, d is the spacing between the slits on the grating, is the diffraction angle, m is the order of the diffraction peak, and is the wavelength of light. This equation shows that the diffraction angle is directly related to the wavelength of light, with a smaller wavelength resulting in a larger diffraction angle.

The Weir equation relates the crystal orientation, diffraction pattern geometry, and experimental conditions to the lattice parameters of a crystalline material in electron diffraction. It is important because it allows researchers to determine the crystal structure of a material by analyzing its diffraction pattern, providing critical information about the arrangement of atoms in the material.
