So when it comes to Electricity, there's AC and DC. Are there other forms of Electricity besides static?
Is Electricity a spectrum?

Electricity is a man-made creation. There are as many kind of electricity as we want there to be, i.e. 1 phase, 2 phase, and 3 phase AC.
It's like asking how many kinds of broadband there are.

>1 phase, 2 phase, and 3 phase AC
That's still AC despite the number of phases.

You're trying to meme, but yes, it is a spectrum.
The mathematical subject of interest is Fourier series. Pretty important in Electrical Engineering, Quantum Mechanics, Functional Analysis, and Dynamical Systems.
Consider the voltage signal:
[math]v(t) = V_{1}cos(\omega_0 t)+ V_2 cos(2\omega_0t) +[/math]
The is the sum of two AC voltages. Since the second term has twice the frequency of the first, the signal is periodic. Specifically with period [math]\omega_0[/math].
The same argument applies if we consider any two signals with integer multiple angular frequency. That is, the result is still periodic with respect to [math]\omega_0[/math].
When I say the "spectrum" of the signal, I am talking about which frequencies have the highest amplitude for their sin/cos function. There is also a "spectrum" to operators on such functions. Using a little complex analysis, you can find spectra for integrals, derivatives, and other operations too. (LTI operators if you are curious.)
The main idea in electrical engineering is to construct systems which may manipulate sums of cos/sin functions like this. The theory is rather complex. Usually, this sort of thing would be covered in a third or fourth course of Analysis. If you were an engineering student, this would be covered any time as soon as your first year, to as late as your 3rd year.

period [math] \frac{1}{2\pi\omega_0}[/math] sorry

I had to study that shit when I was taking courses in human eyesight and the properties of retinal processing of light.
It was kind of interesting to be fair.
