Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

is white light
Again, although the rays have not
been drawn perpendicular to the
interface, that is just for clarity. The
rays actually are perpendicular.
