an electron will jump from an orbit to another orbit and its energy
will change. then from that point
a photon as a light begin to travel very very long way with constant
speed. Also photon has a very very little mass. how so long way it can
travel?

this is not how it works, i know, some
of them depict tha energy level of an
atom in this way, but this is becus thay
are fools, see one calling himself OG

energy level is merely a barrier not an
orbit to an electron, electrons dont orbit

this is a good question indeed, i never
saw been asked here

my answer based on my intuition would be
that photons never travel alone,

then that thay are going through amplifying
stations, which may be aether

this is almost tha same answer to tha question

"how does light know that space in front of it is curved, in order to
be attracted in a black hole? "

Photons are not a propagation model.

<<Now, does not the prize to Einstein imply
that the Academy recognised the particle
nature of light? The Nobel Committee says
that Einstein had found that the energy exchange
between matter and ether occurs by atoms emitting
or absorbing a quantum of energy,hv .

As a consequence of the new concept of light quanta
(in modern terminology photons) Einstein proposed the
law that an electron emitted from a substance by
monochromatic light with the frequency has to have
a maximum energy of E=hv-p, where p is the energy needed to
remove the electron from the substance. Robert Andrews
Millikan carried out a series of measurements over a
period of 10 years, finally confirming the validity of this
law in 1916 with great accuracy. Millikan had, however,
found the idea of light quanta to be unfamiliar and strange.

The Nobel Committee avoids committing itself to the
particle concept. Light-quanta or with modern terminology,
photons, were explicitly mentioned in the reports on
which the prize decision rested only in connection with
emission and absorption processes. The Committee says
that the most important application of Einstein's photoelectric
law and also its most convincing confirmation has come from
the use Bohr made of it in his theory of atoms, which explains
a vast amount of spectroscopic data. >>

Light from an atomic oscillator moves just the same
as light from a television transmitter.

It long way can travel very very far it to do how so.
