Until now the principles of black theatre have remained a mystery for majority of population. Now the time has come to unveil the mystery. Yes, the moment to put you in the picture is here! The following explanation will show that the principles of black theatre are surprisingly simple. Just as any other brilliant ideas, of course. Einstein\u2019s formulation of the law of relation between matter and energy remains, at least for now, the basis for the black theatre: <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

As the black theatre uses light we also have to mention Planck\u2019s law of distribution of light in spectrum of black body. According to his theory the energy is radiated in exactly defined and further indivisible units called quanta. The value of the quantum( n ) equals the frequency ( v ): <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Where ( n ) the value of Planck constant n = 6.626*10-34 joule*second. Applications for black theatre effects derive from the above-mentioned physical laws. As we have already said, matter and radiation affect each other. The results can be such phenomena as refraction, diffraction and polarization of light. Sometimes the energy is absorbed. The absorbed energy can transform into thermal energy or light energy of different frequency or into electric energy if a photoelectric effect occurs. If a colour or black body is illuminated with light of a frequency of 0 then transition of energy on a molecular level occurs and the higher vibration and rotation state of molecules is enforced by a quantum leap. <\/p>

Necessary energy ( delta E )is removed from the light quantum and therefore the spectator can see nothing. Mathematically this phenomenon is described as: <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

which means ( v=v0 ) and the black theatre occurs. Meanwhile the amount of absorbed energy on the stage is increasing so it has to be conducted away to the electro-centre by means of a special system (Back Line) where it supports the output of light equipment and air-conditioning. The chart shows how individual spectral lines appear during energy leap of a valence electron into a different quantum state. Obviously the visible colours are a pleasant experience for spectators as they discover that they can in fact see something! <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Finally, it has to be stressed that the given explanation of the principles of black theatre is purely theoretical. We would like to point out the fact that application of the mentioned theory in practice does not necessarily mean that the theatre will be successful. Human factor can change much of the theory. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
