When an atom absorbs a photon it acquires more energy.
yes , it acquires the energy of the photon.
the direction of the atom and the direction of the laser beam
determine the amount of energy over and above the energy of the photon itself that the atom acquires just like in a classic physics impact , like pool balls colliding on a pool table sort of. <--- layman description but not a guess or speculation.
The impact slows it down, so it loses kinetic energy.
yes , the impact slows the atom down , just like in classical physics.theres a lot more energy in a head on collision
Is the kinetic energy lost greater than the energy of the acquired photon,
I couldn't tell you without knowing the energy of the photon and the energy of the impact and the energy of the atom before and after the impact.
from what I understand from the experiments is that
the only time that the atom will absorb the photon is when
the atom is moving towards the laser beam and the frequencies
of the atom and the laser are exact , which is why he dwelt
on the direction in the video because direction is important
just like in classic physics.
we know that when an atom absorbs a photon the atom becomes
excited , we know that the state of the atom changes , we
know that a atoms frequency changes , and we know that the
electrons orbits move outward from the center.
in this excited state the atom has gained energy.
the atom stabilizes , a photon is emitted , the state changes , the frequency changes , the electrons move closer in towards the center.
in order for the atom to slow down further and further ( or cool down more and more ) energy must be lost from the atom itself repeatedly and the only way possible for that to occur is if the atom emits a photon of a higher energy than the photon that impacted the atom initially.
because a normal change from an excited state to a stabilized state places the energy of the atom back to its initial energy , its frequency returns to its initial frequency and its electrons orbits return to there initial orbits.
and with this experiment we see that energy is lost
because we see the atom slowing down
and the only element involved that could possibly account
for the lost energy would be the emission of a higher charged photon.
so that is where the energy goes !
when the atom emits the higher charged photon the electrons
move closer in to the center than they were initially before
as the atom reaches its slowest energy levels in the millionth
of a degree K its mass has not changed , it still has its electrons , they are simply much closer to the center and moving much slower in there orbits than before the experiment began.
and if my brand of physics is correct then its gravity
has also remained the same.
thus , therefore , and hithertooooo
gravity is due to mass , not energy and momentum as the
QM'ers faith would have us believe or speculate or guess or
the fact that the non-layman said the atoms are in a quantum state. Oops!
probably peer pressure... possibly job security ... perhaps
fear of being labeled a heretic and shunned by the QM congregation because he seems like a truly smart smart person not a stupid smart person.
