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.
Light rays refract when they pass through mediums with different optical densities, causing the speed of light to change. This change in speed results in the light rays bending as they move from one medium to another. The amount of bending depends on the angle at which the light enters the new medium.
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.
A convex lens causes light rays to converge, or refract, towards a focal point. This type of lens is thicker at the center than at the edges, causing light rays passing through it to bend inward.
Converging lenses refract light rays in toward a central point, known as the focal point. These lenses are thicker in the center than at the edges and are commonly used in applications like cameras, microscopes, and eyeglasses.
To determine the crystal structure from X-ray diffraction (XRD) data, scientists analyze the diffraction pattern produced when X-rays interact with the crystal lattice. By comparing the diffraction pattern to known crystal structures and using mathematical techniques, such as Fourier analysis and structure factor calculations, they can determine the arrangement of atoms in the crystal lattice.

They bend or refract
Now suppose that the rays of light are traveling through the focal point on the way to the lens. These rays of light will refract when they enter the lens and refract when they leave the lens. As the light rays enter into the more dense lens material, they refract towards the normal; and as they exit into the less dense air, they refract away from the normal. These specific rays will exit the lens traveling parallel to the principal axis.
No, the lattice spacing of a NaCl crystal cannot be determined with sodium yellow light alone because the wavelength of light used for diffraction needs to match the spacing between planes in the crystal lattice. Since the lattice spacing of NaCl is much smaller than the wavelength of sodium yellow light, other types of radiation such as X-rays are typically used for diffraction experiments to accurately determine the lattice spacing.
Light rays reflect when they hit a concave mirror. The parallel rays of light converge at the focal point after reflection.
The bevel of the window made the light refract into a rainbow.
The idea is that, due to the small wavelength of X-rays, atoms can serve as a diffraction grid - causing diffraction patterns. (If you don't know about diffraction, I suggest you search in the questions for "diffraction", or ask a separate question for diffraction.) Crystals are good for this, because of their regular structure.
