From the post "What If The Particles Are Photons?" dated 12 Dec 2017,
\(f=\cfrac{c}{\lambda}=\cfrac{8^3}{18}\pi^2=280.74\,Hz\)
we can have,
\(f=3*280.74\,Hz=842.21\,Hz\)
But,
what is \(w\)? to realize such a 3D confinement portal. It is hoped that with
\(w\gt842.21\,Hz\) and
\(w\) being prime, we may have a prime dialed portal to walk into and walk out.
Just science friction.
