"frequencies at which simple viruses could be shaken to death."

"Rife believed bacteria or viruses inside tumors emitted specific electromagnetic frequencies (EMFs). He developed a microscope he claimed could detect EMFs from bacteria and viruses by the color of their auras.
In the 1930s, he developed another machine called the Rife Frequency Generator. He claimed it produced low-energy radio waves with the same frequency as cancer-causing microbes. He believed sending this frequency to the body would make cancer-causing microbes shatter and die. This frequency was called the mortal oscillatory rate."

"Second signal out of sync with the first to fill in gaps" Start @ 3:33
"We can also see what happens when the two waves are superimposed 180° out of phase with one another. In this instance, at any spatial point, the summation of the electric and magnetic fields are vector zeros, such that both the electric and magnetic field components are mathematically cancelled, depicted in this case by the resultant red 'flat-line.'"
"By combining two EM waves in this way, one does not nullify them i.e. cause the electric and magnetic components to “cease to exist.” But rather, the electric and magnetic components are “in-folded,” to produce a beam of an entirely different qualitative nature, with vastly different properties. This is a scalar beam."

"so that multiple waves were hitting the cancer cells would be like increasing the power of the signal."

"This wave is necessary in order to deliver the frequency wave deeper in to the body."
