Seed dispersal syndrome

Anemochory (seed dispersal by wind)

We imagine that this has taken a new form and rapidly spreads

“Epizoochory is the accidental dispersal by animals” — this is what I did with the poor tree from Ridgewood reservoir.

Calculating a reasonable windspeed and wavelength:

A windspeed of 1.5 m/s is a light breeze on the Beaufort scale, which seems reasonable for dispersing seeds. Using the physics of wavelength and windspeeds in the ocean, it can be calculated that such a windspeed will have a wavelength of 1.5 m. This is a frequency of 200 MHz. That is within the radio frequency spectrum. Calculated using: http://hyperphysics.phy-astr.gsu.edu/hbase/watwav.html#c3

Instead of using electromagnetic waves, it could be sound waves which intercepts:

So reading about sound :

Calculating sound waves: saying sound waves travel at 340m/s, we can use this to calculate the wavelength

So this would be for me: wavelength: 1.5 meters = 340 / x

so x = appr. 225 hz

So my frequency will be 225 hz 

Instead: we use the tree input as a modulation of the sine wave
