Hygens principle of secondary wavelets

Hygens proposed a theory to explain the transmission of waves in a medium, which Hygens called the theory of secondary wavelets, for this Hygens made the following hypothesis that ...
1. When waves emanate from a wave source located in a medium, the particles of the medium around the wave source start vibrating. The surface in which all the particles located in the medium vibrate in the art is called the waveform. If the wave source is point then the wavelength is spherical. It happens that the waveform is flat at a great distance from the wave source.
2.Each particle of the medium located on the waveform acts as a new wave source from which new waves emanate in all directions. These new waves are called secondary waves. Secondary waves in the medium move at the same speed as the primary waves.
3. If at any moment, the secondary waveforms, ie the surface touching them, are drawn, then this zone displays the new position of the waveform at that moment.
