Define a wavefront. Using Huygens principle, verify the laws ofreflection at a plane surface. |
|
Answer» a wavefront is the locus of points characterized by propagation of positions of identical phase: propagation of a point in 1D, a curve in 2D or a surface in 3D. For an electromagnetic wave, the wavefront is represented as a surface of identical phase, and can be modified with conventional optics |
