The nature of light
Thinking the dark matter as a medium for light propagation we can get a
classical math form of a standing wave, i.e. the light ray is a simple
phenomenon of interference between a medium wave and pulsing particles.
The raising of central points in the WG theory is founded on ample
physical evidences not by subjective hypothesis. It is especially distinct from
Einstein’s relativity. As is well known the assuming premises of the theory of
relativity is the Instantaneous Principle and Light Speed Constancy but has no
mentioned about the mechanism of light propagation.
The four central points of the WG theory have provided some basic
conditions for revealing the mechanism of light ray propagating in free space,
as well as some descriptions on moving states of light.
Assuming a light source is stimulated to emit a pulse of light matter WG,
which enters the surrounding WG ether to induce a ether wave. The frequency of
the wave is related and corresponds to the energy and speed of the WG particle
pulse. Furthermore, the wave inevitably reacts on the light source and
constrains the stimulation by its frequency. Consequently the pulse will vary
with a change in the frequency. In the wave theory there is a sufficient mature
mathematical approach to deal with this problem. This
is a typical standing wave problem, i.e. the superposition between both the WG
pulse from the light source and the WG ether wave will produce interference to
form a standing wave. These motion properties determine the particular
phenomena that the energy of the optical wave is discrete; it possesses the
properties of the wave. At the same time it also possesses some particle
properties, For instance, the property of impulse, light pressure etc.
also point out that we usually measure the energy emitted by some light source
excluding all the mass-energy of the medium itself. So that is why
astrophysicists get the photo-metric mass excluding the medium mass in all space
i.e. those photo-metrical principles used to measure the universal mass before
are not correct, not because the medium is dark or light, invisible or visible.
So I prefer to call it, as Light matter WG not the Dark matter.
most significant experiment for verifying the above mechanism is the experiment
on “photo-electric effect”.
5.2 A powerful supporting experiment to “WG” theory ¾ the “photoelectric effect”
The experiment on “photo-electric effect” is introduced in some
senior school textbooks. When an electron gets the irradiation of a light beam
it will escape from the cathode. There is a threshold of the frequency to the
light beam, namely the infrared limit. When the frequency of the light beam is
larger than the infrared limit, the escaping electrons can be detected, no
matter how small the irradiation quantity is. On the other hand, no electron can
be detected if the frequency is less than the threshold, no matter how large the
quantity of the irradiation is (or named flux of the light). It is commonly
accepted that the frequency of light determines the energy a light ray possesses
but not its amplitude.
In the following I would like adopt the principle of “WG theory” to
discuss the “photo-electron effect”. An electron oscillating in the cathode
tends to escape from the cathode and is attracted by this cathode at the same
time. During the period of oscillation, if the motion of the electron is
subjected to an action of the light pulse, when the frequency of the light pulse
is large enough during the period of oscillation the electron can absorb enough
WG to increase the energy to escape the cathode. Therefore, the escaping time is
neither “comparably longer to accumulate as is requested by the wave theory,
nor “needs almost no time” statistically as is described in the elastic
collision theory. There is a fixed, but very short time interval for the
electron to escape from the cathode. It is not incidental, that the experimental
data is perfectly in agreement with the theoretical mechanism. As for the
duality of the light and other experiments, under the concept of “WG” theory
they are very easy to explain and understand this being so I am not going to
dwell on them. In the following chapter I would like to discuss the relationship
between the WG theory and essential mechanism of strong interaction.
