Diffraction & Gratings . Diffraction occurs whenever a wave passes an obstruction, either an aperture, a barrier or even a simple edge. The result of any diffraction is that the wave will spread out, beyond the obstruction, in to the area normally thought of as being in shadow. The amount of diffraction will depend on the both the size of the obstruction and the wavelength of the wave. Because ...
