### Wavefront

In physics, a wavefront is the locus of points having the same phase: a line or curve in 2d, or a surface for a wave propagating in 3d. Since infrared, optical, x-ray and gamma-ray frequencies are so high, the temporal component of electromagnetic waves is usually ignored at these wavelengths, and it is only the phase of the spatial oscillation th...

### Wavefront

A set of points at which the phase of vibration of the physical quantity associated with a wave is the same.The surfaces joining all points of equal phase are known as wavefronts.

### wavefront

an equiphase surface common to all the components of the vectors of an electromagnetic field, when such a surface exists NOTE - A wavefront is orthogonal at each point to the real part of the wave vector relative to this point.
