Be more specific...because Visible light "Rays" are diffracted in those ways.
When rays fall on a diffraction grating normally (perpendicular to the surface), they spread out evenly across the grating, maximizing the interference pattern observed. This is because the angle of incidence affects how the waves interact with each slit on the grating, influencing the resulting diffraction pattern. Normal incidence ensures optimal alignment for constructive interference.
The angle of minimum deviation in a diffraction experiment is the angle at which the diffracted light rays are the most spread out, resulting in the best separation of the different colors. It is typically smaller than the angle of the first diffraction minimum to achieve maximum dispersion.
Bragg's law explains the angles at which X-rays are diffracted by crystal lattice planes, producing interference patterns known as diffraction lines in powder diffraction. These diffraction lines represent constructive interference between X-rays scattered by the crystal lattice. The spacing between the crystal planes and the angle of incidence determine the positions of the diffraction lines observed in the powder method.
Diffraction phenomenon is broadly classified into two categories: (a) Fresnel diffraction (near-field diffraction) The interference is considered to take place from different parts of an aperture when either the source or screen or both are at finite distance from the obstacle.(b) Fraunhoffer diffraction (far-field diffraction) The interference is considered to take place from different parts of an aperture when either the source or screen or both are at finite distance from the obstacle.== ==
Crystals can refract light rays through their orderly arrangement of atoms, but they do not diffract light rays because diffraction requires a periodic arrangement of atoms at a scale comparable to the wavelength of light. Crystals have a regular repeating structure, while diffraction typically occurs with structures on the scale of the wavelength of light.

Actually cystal is a three dimensional grating with grating element(interplanar spacing)as of the order of 1 angstron unit. Also the wavelength of X rays is of the order of 1 angstron which satisfies basic condition of diffraction(Bragg's law). Gamma rays are not used for the same reason as well as gamma ray production is not high enough, difficult to focus and high intense enough to create particl and antiparticle.
The internal ordering of mineral crystals was first detected using X-ray crystallography. This technique involves directing X-rays at a crystal and measuring the angle and intensity of the diffracted X-rays to determine the structure and arrangement of atoms within the crystal.

If the lens is convex, they will be diffracted and focused to a point, after which they will spread out. If it's concave, they will be diffracted so that they spread out without first concentrating.

X-rays with wavelengths of 128 pm was used to study a crystal which produced a reflection of 15.8 degrees. Assuming first order diffraction (n = 1), what is the distance between the planes of atoms (d)
