Jeans' Length As Oscillation Wavelength
The Jeans' Length is the oscillation wavelength below which stable oscillations rather than gravitational collapse will occur.
where G is the gravitational constant, is the sound speed, and is the enclosed mass density.
It is also the distance a sound wave would travel in the collapse time.
