Strawman; that is _not_ what I meant.
[The energy that a photon has, and transports, is always
E_γ = p c = ℎ f = ℎ c∕λ,
and the energy that electromagnetic (EM) radiation transports can therefore
be described by
E_r = n E_γ = n p c = n ℎ f = n ℎ c∕λ
where n is the number of photons traveling through a *cross-section* of
space.
So it is true that for the same amount of *total* energy to be transported
by EM radiation with longer wavelengths/lower frequencies than shorter
wavelengths/higher frequencies, more photons are required to travel *through
that cross-section*: the *intensity* of the radiation would have to
increase.¹]
But that has nothing to do with your assertion that there would be more
photons located within a *volume* then.
And it has nothing to do with your invented property of photons of
“interaction range”, which you mistakenly equate with wavelength.
Because photons have mass zero [1] and are the carriers of the EM
*interaction*, the range of the EM interaction is infinite; the
wavelength/frequency of EM *radiation* is irrelevant in that regard.
AISB, you are confusing the properties of the wave interpretation of EM
radiation with those of its particle interpretation. They are related (see
above), but not in the way that you think.

No, just hinting at your own obtuseness.

As you have demonstrated.

No, that you have a misconception there is evident from your statements.

¹ That is why e.g. gamma radiation is life-threatening and e.g. human-
visible light usually is not: the former has the ability to transport
much more energy per unit time than the latter. It is also why you get
sunburn and photokeratitis, and can get skin cancer, only after
*prolonged* exposure to sunlight – the shorter the thinner the ozone
layer is above you, filtering out UV radiation.
