"Redshift - Does wavelength change?"

Silly Vesselin Petkov has discovered that the gravitational redshift
is due to the variation of the speed of light in a gravitational
field, in accordance with Einstein's 1911 equation c'=c(1+V/c^2), but
Criminal Tom Roberts fiercely confuses Silly Vesselin Petkov and does
not allow him to leave the zombie group in Einstein criminal cult and
become hypnotist.

Silly Vesselin Petkov confused forever:

Silly Vesselin Petkov: "It is usually assumed that both frequency and
wavelength of a photon in the gravitational redshift change whereas
its velocity remains constant. In this note we shall show that it is
the frequency of a photon that does not change whereas its velocity
and wavelength change."
