Messing with my pet theory, I need help. I can't find my old book but what is the formula for the angular frequency of a light wave by wave length and phase velocity. I can't remember but it's simple.. Can't find it but I am sure I am looking in the wrong place

Of course as soon as I ask i find it online.. Thanks anyway

Frequency is velocity divided by wavelength. I recall that much.

When I had a quick look online, it took me back a bit.. I never had to work with light but mechanical vibration used to be what put meat on my table and in a rather odd way, the formulae were somewhat nostalgic.

To be honest Dan, I was wondering if you were devising some high tech fishing device!

No help here, I'm still trying to remember what the angle of the dangle is inversely proportionate to.

I was wrong. Found the following in the Urban Dictionary.

"the angle of the dangle is inversely proportional to the heat of the meat, provided that the maxis of the axis, and the gravity of the cavity, remain constant."

""For a smart material to be able to send out a more complex signal it needs to be nonlinear. If you hit a tuning fork twice as hard it will ring twice as loud but still at the same frequency. That's a linear response. If you hit a person twice as hard they're unlikely just to shout twice as loud. That property lets you learn more about the person than the tuning fork".

No no no! The angle of the dangle is equal to the mass of the ass times the square of the hair. Where the hell did you go to school?

Ha! So I was right. It is all about ruddy fishing!

If you dangle the angle of your line
You'll catch that fish well in time
Pull the hook and stick it up her
And get her home in time for supper

There. Not a knob gag in sight.

"Angular frequency is a measure of the frequency of an object varying sinusoidally equal to 2π times the frequency in cycles per second and expressed in radians per second."

But I don't care what they say. If you are having sinus problems, Dan, see a GP and keep away from that radiation.

The most general form of a harmonic wave is given by ψ = A cos[k(x - vt)] , where v is the phase velocity and k is the wave number. Expanding this we have ψ = A cos(kx - kvt) . We know that the argument of the cosine must be dimensionless, so the expression kvt must be dimensionless, thus kv must be an inverse time, or the angular frequency of the wave (we know it is an angular frequency and not a regular frequency since we want the argument of the cosine to be in radians, which are dimensionless). Thus σ = kv . But the wavenumber is just k = 2Π/λ

But you can simply it further. This is what I needed

Now, all we are talking about is a wave, either of sound or light. It's moving evenly (sinusoidally) up and down.

It occurs to me that theology and science differ in an important way. Theology makes the ineffable seem simple, and science makes the simple seem complicated.

Use a fast uranium-235 or plutonium-239 based self-sustaining chain reaction inside a cylinder of lithium VI deutride. Your original question will be almost immediately answered.
