What causes the photon to move at different frequencies?

A photon does not "move at a frequency," but at the speed of light. The electromagnetic field can oscillate at any frequency, and therefore photons can have any frequency.

Do you mean that the oscillation caused by the photon sub particles once it
influenced by the radiation generator instrument / field ?

How the electromagnetic field affect the photon ?

The sentence you wrote in post #3.

How the electromagnetic field affect the photon ?
The electromagnetic field does not affect the photon. Photons are elementary excitations of the EM field.

cuz that statement .....

didn't mean anything

How the electromagnetic field affect the photon ?

the EM field DOESNT affect the photon
start doing some reading on how EM fields are generated, and what they consist of

there's a couple

you will find that frequency of a photon is a measure of the energy of a photon. If the frequency changes then the energy changes, perhaps as the result of a collision.

It's difficult asking questions when you don't know much of about the language used to describe a proper answer.
It turns out that electromagnetic energy and their interactions can be described in many cases via waves, that is spread out phenomena when things are large. Radio transmitters and receivers would be an example. But at the tiny level of atomic particles, that description fails to match experimental evidence. At such tiny scales it turns out that electromagnetic interactions take place in discrete levels as point particle interactions; we call those discrete packets of energy photons. They have various energies which means they are associated with electromagnetic fields of different frequencies.

As described in the Wikipedia article referenced in an earlier post, material objects [atomic and sub atomic particles] ".. that emit and absorb light do so in amounts of energy that are quantized (i.e., they change energy only by certain particular discrete amounts and cannot change energy in any arbitrary way)." As described, Compton scattering of single photons by electrons, and black body radiation descriptions, illustrate the quantized nature of light...it occurs only in discrete rather than continuous energies. When an atom absorbs or emits some electromagnetic radiation it does so in discrete amounts....that is a photon is emitted or absorbed, say in an atom, never as 'one and a half' photons.....

Is there an experiment that demonstrates that the undulating movement of the photon is due to the hit of the electromagnetic field particles at it without any connection to the photon sub particles internal interactions ?
And if the photon sub particles not exists , how photon influenced by a specific electromagnetic field from the range ?

The photon doenst have an undulating motion

photon sub particles ?? what do you think they are ? where did you read that ?
