Lesson Twenty One

Lesson Twenty One

Purpose: To see if similar living things interfere with each
other when put on the plate together.
Materials: Two identical living insects or very small living
things.
Method: Find the broadcast range of each one separately and
then together on the plate.
Note: Identical living things do not interfere with each others'
frequencies.
Lesson Twenty Two
Purpose: To see if different living things interfere with each
other when put on the plate together.
Method: Find the lower and upper end of the broadcast
range of two different living things, such as a fly and a beetle or
2 kinds of flies or beetles. Then put them on the plate together.
Notice there is no resonance in the accustomed range for either of
them. They are interfering with each other on the plate.
Now add the 2 lower ends, then the two upper ends. Also
subtract the 2 lower ends, then the two upper ends. For example
imagine two insects, one with a spectrum of 1000 to 1090 KHz,
the other with a range of 1050 to 1190 KHz. Adding the lower
ends gives us 2050 KHz. Subtracting the lower ends gives us 50
KHz. Adding the upper ends gives 2280. Subtracting the upper
ends gives 100. Now search for resonance at 50, 100, 2050,
2280 KHz. (These last two may be outside the range of your
frequency generator. Choose more primitive life forms which
have lower frequency bandwidths to stay within your limit.)
Notice that you hear resonance at exactly these frequencies
and not above or below them. This is evidence for modulation of
the frequencies: namely fusing them together.
