WebWithout having any evidence to support his claim on the periodic arrangements of atoms in a lattice, he further postulated that the crystalline structure could be used to diffract x-rays, much like a grating in an infrared spectrometer can diffract infrared light. Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the word diffraction and was the first to record accurate observations of the phenomenon in 1660.

WebThat illustrates that sound waves diffract, and moreover that they diffract much more than light waves under these circumstances. That's because the wavelength of sound waves is comparable to the other length scales in the situation, whereas the wavelength of light waves is much shorter.
