diffraction
意味: The bending and spreading of waves when they encounter an obstacle or pass through a narrow opening, resulting in interference patterns.
Diffraction occurs with all types of waves, including light, sound, and water waves. It is most noticeable when the size of the obstacle or aperture is comparable to the wavelength. X-ray diffraction is a key technique in structural biology, used to determine the three-dimensional shapes of molecules — famously, the structure of DNA was revealed through X-ray diffraction images.
