noun

dif·frac·tion di-ˈfrak-shən $How to pronounce diffraction (audio)$

: a modification which light undergoes especially in passing by the edges of opaque bodies or through narrow openings and in which the rays appear to be deflected

also : a similar modification of other waves (such as sound waves) or of moving particles (such as electrons)
