Popis: The problem of vector theory of amplitude zeroes is discussed. The amplitude zeroes can be of two kinds. In the vicinity of the first kind of zeroes, polarization is linearized, the phase does not have singularity, and a wavefront does not have dislocations. In the vicinity of the second kind of zeroes, polarization is elliptical, a phase has singularity, and a wavefront has a screw dislocation. The experimental results are given.
