She is trying the "old African-American grandma that lives next door, I am just like you" character too hard… or like she owns and hair salon/fried chicken business.

Negative.. but your words reminded me of Pirates of the Carribean .. when the flash happens as they go into the Upside Down…I imagine as we leave the Upside Down and return right side up… there will be a bright flash…

Sine Waves. 'Unified" Synchronized…. parallel…

 

A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation. A sine wave is a continuous wave. It is named after the function sine, of which it is the graph. It occurs often in pure and applied mathematics, as well as physics, engineering, signal processing and many other fields. Its most basic form as a function of time (t) is:

 

y ( t ) = A sin ⁡ ( 2 π f t + φ ) = A sin ⁡ ( ω t + φ ) {\displaystyle y(t)=A\sin(2\pi ft+\varphi )=A\sin(\omega t+\varphi )} y(t) = A\sin(2 \pi f t + \varphi) = A\sin(\omega t + \varphi)

 

where:

 

A = amplitude, the peak deviation of the function from zero.

f = ordinary frequency, the number of oscillations (cycles) that occur each second of time.

ω = 2πf, angular frequency, the rate of change of the function argument in units of radians per second

φ {\displaystyle \varphi } \varphi = phase, specifies (in radians) where in its cycle the oscillation is at t = 0.

When φ {\displaystyle \varphi } \varphi is non-zero, the entire waveform appears to be shifted in time by the amount φ {\displaystyle \varphi } \varphi /ω seconds. A negative value represents a delay, and a positive value represents an advance.

The oscillation of an undamped spring-mass system around the equilibrium is a sine wave

 

The sine wave is important in physics because it retains its wave shape when added to another sine wave of the same frequency and arbitrary phase and magnitude. It is the only periodic waveform that has this property. This property leads to its importance in Fourier analysis and makes it acoustically unique.
