They did give us a wave frequency. 719hzSable wrote:We have no wave function to start with, so how can we use the Equation to project that function forward or back?
You would see a lower case omega sign in there if there was a frequency to the wave. And, it isn't the standard wave that you're thinking about. If it is an "ocean" wave, then there only a limited area that it can exist. It would have to be between some plates or something. Otherwise, the wave function appears as a "hill" or something, going to 0 at +/- infinity.Dunia wrote:They did give us a wave frequency. 719hzSable wrote:We have no wave function to start with, so how can we use the Equation to project that function forward or back?
Maybe another portion of the wave function will arrive later.
/EDIT: Didn't they also give us pulse as well? That would give us wavelength right?
I didn't say that the wave function's frequency was 719 hz. I said that for a light pulse. Read my post again. And that psi times psi_bar is the wave function squared. But, for a problem in QM, there can be a wave function that has an infinite number of possible wavelengths. Look up the infinite well problem in a Wiki. In this case, it is the lowest energy one, hence the "ground state" notation.Sable wrote:A wave function is not a wave length.
An expression of 719Hz indicates an oscillation in some medium of 719 times per second in a wave form.
This is not a wave function.

That's the Wiki on a wave function.
We have not, as near as I have been able to tell, been given a wave function.
I'm trying to get up to speed with my limited physics knowledge.Properties of the Wave Function
wave speed (v) - the speed of the wave's propagation
amplitude (A) - the maximum magnitude of the displacement from equilibrium, in SI units of meters. The amplitude is indicated in blue in the picture.
period (T) - is the time for one wave cycle (two pulses, or from crest to crest or trough to trough), in SI units of seconds (though it may be referred to as "seconds per cycle").
frequency (f) - the number of cycles in a unit of time. The SI unit of frequncy is the hertz (Hz) and 1 Hz = 1 cycle/s = 1 s-1
angular frequency (omega) - is 2pi times the frequency, in SI units of radians per second.
wavelength (lambda) - the distance between any two points at corresponding positions on successive repetitions in the wave, so (for example) from one crest or trough to the next, in SI units of meters. The wavelength is indicated in red in the picture.
wave number (k) - also called the propagation constant, this useful quantity is defined as 2 pi divided by the wavelength, so the SI units are radians per meter.
pulse - one half-wavelength, from equilibrium back
Some useful equations in defining the above quantities are:
v = lambda / T = lambda f
omega = 2 pi f = 2 pi/T
T = 1 / f = 2 pi/omega
k = 2pi/omega
omega = vk
Just thought Id throw that in.The Forerunner were somehow capable of advanced message carrier waves in Slipspace. This way, messages could travel at great speeds throughout their empire.
Heh, maybe chimps are planning to take over, aka The Planet of the Apes. But, the infinite well is really extraneous info. I think I'm reading way too deep into this. I think the main message to carry away is that the Forerunner and Humans use the same maths and sciences, further indicating a connection. I'm going to end my ramblings about QM because its starting to flood the boards, and is probably unimportant. But I think that we all learned something new from this.Dunia wrote:I looked for the infinite well problem in Wiki and had no results. It did bring up the "Infinite Monkey" theorum.
