Examples

  • When X-rays are introduced into a material, they are diffracted in a characteristic pattern based on the regular, repeating crystalline structure.

  • All right, so light starts from the source, hits the aperture plane and then gets diffracted by the apertures and winds up on the image plane over here.

  • This ordering of the molecules means that when we fire X-rays at a crystal, it diffracts or scatters the beam into hundreds of intense rays.

  • When the grating is present, a laser beam passing through the modulator crystal is diffracted, essentially splitting into two output beams, called first-order and zero-order.

Morphology

diffract = fracture (semi-transparent) = dif + fract

Formally built from the prefix 'dif-' (variant of dis-, 'apart') + the combining form 'fract' ('break'), but 'fract' is not a standalone word and the technical sense for waves is metaphorical/specialized.

Etymology

Diffract comes from Latin parts meaning 'apart' (dis-) and 'break' (fract), the same root you see in fracture and fragment. Think of a wave 'breaking apart' and spreading out when it passes a small gap or edge, which explains why diffract means to bend or spread and make a pattern.
