Propagation Definition and 457 Threads

Always the easy things we forget... I know how errors propogate through multiplication or division when every term has an error, but how do I propagate errors in equations when only one term has an uncertainty? I want to say just multiply and divide the uncertainty value by the constants, i.e...

I am starting a new thread on this subject because I feel that the subject under discussion is of the greatest importance. The “aumic” theory on the nature of light brings to our attention , for the first time , several peculiar and interesting aspects on the nature of light and indeed of all...

Ed Fomalont of the National Radio Astronomy Observatory and Sergei Kopeikin from the University of Missouri in Columbia, performed an experiment on 18 September 2002 using an array of radio telescopes around the world they observed light from a faraway galaxy bend as the planet Jupiter passed...

Hellfire, you just going to make chroot :mad: Whilst you queastion and reasonning are quite sound, the response by chroot is not so. So let me elaborate on this:In quantum field theory, particles (and thus also photons) are excitations of fields. The the position is not a dinamical...

In special relativity it is often claimed that light does not need a medium to propagate. In quantum field theory, particles (and thus also photons) are excitations of fields. The the position is not a dinamical variable as such anymore, but just a label for each of the field excitations in...

I was asked this question Why is there an ideal wavelength for propagation in optic fibres? a. Light absorption losses are minimum b. The fibre has its greatest transparency at the ideal wavelength c. Rayleigh scattering is greatest at this wavelength d. Total internal reflection...

When a single photon is produced by a point source, and detected by an array of detectors placed on the surface of a sphere around the point source, would only one of the detectors pick up the photon, or would only some of them pick it up, or would all of them pick it up, assuming no extraneous...
