You refer to doppler in air regularly as a correllation with light
propagation; so where is the energy of sound? in the frequency or the
AMPLITUDE?

Infantile idiot! How childish is it to deliberately misconstrue a
reminder?
(vacuum) was put in to remind you that at all times I discuss light
propagation in abscence of any other material------which you either
knew and are deliberately deceitful to suggest otherwise, or are just
plain stupid.

Enough, that a beam of them can support (overcome the gravity acting
on) a massive particle. FYI that just confirms the KE of the photons,
and conservation of energy.

The Pakis could do with another "rotational" bowler, since the "spin"
word has apparently been copyrighted by AE!

A certain radio crystal emits a certain wavelength, right?
Now take the crystal on a moving spaceship, and the frequency alters.
So, as the wavelength CANNOT alter, and the received frequency DOES,
how DOES c not alter???????????????
