One paper claims that the flyby anomaly only exists because NASA scientists forgot about the transverse Doppler effect. If that's true, why is it still called an anomaly? Why isn't everyone banging their heads on walls and thinking, "D'oh! I can't believe I forgot about that!"? If it's not...

I understand that light propagates as a transverse wave -- does this mean that the momentum carried by a photon is perpendicular to its path? Thanks for the help.

hi all, pretty sure this is the wrong place to post this but it is a quick one so... is a sine wave always transverse? thanks

In the classical picture of an electromagnetic wave, the wavelength is specified along the direction of travel. However, with EM shielding that is using a grid (microwave, chicken wire), I've heard that so long as the spaces are less than the wavelength, you will achieve electromagnetic...

I heard that transverse wave can not travel trough gas and liquid then how can light travel through all the way to earth? Is it because the light is the collection of small energy particles called photon and not just behave as the normal waves?

There is no "Transverse Gravitatonal Redshift" There has been a lot of noise on this forum lately about A. Mayer's so-called "Transverse Gravitational Redshift." It is not difficult to prove that no such effect exists, yet I have not seen anyone post a calculation to prove it. I have therefore...
