**6
- Derivation of the wavelength**

**6.1
- Conditions**

The basic condition after chapter 5.2 is that a whole number of oscillations fits once around the earth and thus forms a standing wave, as a steady state. In a first attempt counts to the surface: | ||

The wavelength corresponds
to a certain distance on the circumference of the earth.
In the following illustration 6.1 the situation is
illustrated for an oscillation. |
||

and | ||

If one looks
at this situation from the earth centre, a certain angle a can be assigned to every
oscillation. |
||

Then all together as a basis appears: | ||

For reasons
of the illustration a factor has remained unnoticed, in
the previous representation, which must be included now
in the consideration: the ball figure of the
earth.It must be still taken into consideration that the wave propagation linearly takes place, and
not along the curved earth surface. Hence, in the
consequence it requires a modification of the basic
equation. |

**6.2
- The derivation**

After the Huygens
principle the points A, B,
C in Illustration 6.1, so the extreme
points, serve as source points of the
standing wave.Electromagnetic waves spread out spherically
from a point and if point B is the
starting point, corresponds the distance BDC = h
to the way of the wave. Because there is a steady state and it is enough to look the way of the wave from a source to the next source. |

The triangle MCD is right-angled in the point D and it counts: |

Change after lambda dash produces the corrected wavelength: |

**6.3
- The frequency equation**

The connection between wavelength and frequency is: |

With thus
arises the equation for the earth frequencies: |

c
stands for the speed of light, R for the radius of the earth, n n for the number of oscillationsBecause the earth is, however, no
perfect sphere, there to the poles flattened. Here exist
two radii: the |

Pole radius :
11,79 HertzEquator radius : 11,75 Hertz |

The appearing difference
may seem unimportant at first sight. However, in case of
farther consideration a significant difference arises. In
the next chapter 7 this will become still clearly
recognizable in the subject sferics.Remark: Nikolas Tesla declared at his time that the earth frequency lies near 12 hertz. |

**6.4
- A relation to the pole axis of the earth**

Another connection to the pole axis is given by the basic oscillation. If one declares for the first basic frequency the general solutions, these are: |

n |
f |
Pole
radius |
Equator
radius |

1 | 11,79 Hz | 11,75 Hz | |

2 | 16,674 Hz | 16,618 Hz | |

3 | 23,58 Hz | 23,5 Hz |

For n=1 the general equation for the
wavelength is: lambda = 4RAnd one receives
the identical result if a rod of the length of the Pole
axis freely swung at both ends. As well as in the following illustration
6.2 shown. |

Illustration 6.2 - Earth and basic oscillation |

Here the analogy is a
massive rod which both ends are free. If this rod is
moved now into oscillation, the basic oscillation
starting longitudinal flexural vibration corresponds to
the picture 6.2. (see also „Physik“ von Gerthsen, Kneser, Vogel – Kapitel 4.1.5) |

**6.5
- The frequencies of the earth**

If one puts successively for n the values
1,2.3 ... in the above equation for the frequency, the
basic frequencies of the earth arises. The following
table contains the first 30 frequency oriented on the
pole radius. |

2 | 16,6740 Hz |

3 | 23,5806 Hz |

28 | 210,2762 Hz |

29 | 217,7784 Hz |

30 | 225,2807 Hz |

To this
basic frequency suitable harmonivs still appear, i.e. one
must form in addition only the integer multiples. (One calls harmonics as general integer multiples of an elective basic frequency) |

In the book the frequencies are still
declared which are oriented on the equator radius. |

**6.6
- A further derivation**

In the book the derivation is still declared for a farther frequency equation. |
