Is there any way to accurately measure the wavelength of a single,
individual photon? How precise could such a measurement be?
I will be satisfied if the "measurement" consists only of confirmation
that a photon from a monochromatic source has the expected value,
as long as it has sufficient precision to provide useful information
about the photon. But it would be better if the wavelength could
actually be measured without knowing beforehand exactly what
the wavelength should be.
If the former is possible but the latter is not, I would like to know
anything you can tell me about what makes the difference.
