For each resolvable spot of deflection in the far-field, the near-field wavefront must be rapidly tilted by one wave. Nonlinear optical mechanisms based on the Kerr ...

From a flat mirror, designer light — Harvard School of Engineering
... It has been recognized since ancient times that light travels at different speeds through different media. Reflection and refraction occur whenever light encounters a material at an angle, because one side of the beam is able to race ahead of the other. As a result, the wavefront changes direction. ...
