Diffraction PHYS261 fall 2006

Diffraction PHYS261 fall 2006. Diffraction is a phenomenon when a wave that passes through an aperture or around an obstacle forms a pattern on a screen. What causes diffraction is interference of an infinite number of waves that are emitted by the points of the aperture.
