Does "Slow Light" Respond to Gravity--continued. In regards to Zz's reply--Zz states: In other words, not that much different than shinning a light onto a black paper. This is why I wanted to know in the beginning why the OP thinks that gravity plays a role here. Why is gravity suddenly...

Does "Slow" Light Respond to Gravity Terrific reference and lead for further reading, Dr. Claude. Thank you.

Does "Slow" Light Respond to Gravity Light in a vacuum traveling near a massive object will be deflected towards the mass because gravity acts on light just as it does on matter. No? I'm asking if this same thing occurs in a medium that slows light enough to measure visually.

Does "Slow" Light Respond to Gravity "Lene Vestergaard Hau (born in Vejle, Denmark, on November 13, 1959) is a Danish physicist. In 1999, she led a Harvard University team who, by use of a superfluid, succeeded in slowing a beam of light to about 17 metres per second, and, in 2001, was able to...

Oh, I get it, now. The wavelength can be changed arbitrarily but the energy in it is in constant inverse porportion to it. And free photons are not quantized in free space. Hmm...but how would you know that? Free photons can't be measured, can they? Only after their wave function collapses? No?

Yet, isn't Planck's constant a quantum function which relates energy to wavelength?

How can discreet quanta of photon energy make up a continuous electromagnetic spectrum, whose wavelengths are any arbitrary value? Is there overlap of quanta, temperature dependency, or so many finely divided energy levels that the spectrum just appears continuous? Electron energies are...
