If, therefore, the quantum flies back into the original direction, it has regained
its original frequency, and the velocity of both participating atoms is simply ex-
changed between them.
Hence, not the slightest redshift can occur in the original direction of observa-
tion, either.[10]
Neither do I see any possibility for an effect of higher order. If it were present,
it would not play any role because the change in frequency as a result of the term
is very small already, e.g., for Hg Δν upon reflection:
or
[11]
thus . Even here, if the redshift were zero, one therefore ought to
have
104
individual processes to make the shift equal to the Doppler width, which
amounts to ≈
10–3
Å; therefore, an effect of higher order, if it were present, would
escape observation. In the hope that you will grant me my argument, I am, in ut-
most respect, very sincerely yours,
W. Orthmann.
