On this slide we show how to regard the magnitude of the stress, by
using one wave envelope as "virtual ground." In
the top diagram, the original Efield stress of each wave has a
magnitude of 5, and the composite stress wave now has a magnitude of 10,
in whatever units we choose to express them.
We
show in the bottom diagram that during one half cycle we have
compressive stress in the virtual particle vacuum flux, and during the
second half cycle we have tensile stress.
This
shows the wave is like a sound wave in the gaseous molecules of the air.
However,
this wave has one difference. It also oscillates time, and thus
has at least one additional degree of freedom, compared to ordinary EM
waves.
In
fact, this wave can be made ndimensional and hyperspatial.
As a
first order approximation, we can treat such a wave in
a spatial fashion, if the wave is not too great in magnitude and
the relativistic oscillation of time and inertia is not too large.
