Thank you jtbell

please can someone answer my question?

Well expressed jtbell so is that what it happens or should it be rotated 90 degrees like: The bright and dark bands are each oriented horizontally, perpendicular to the slit(s), but they are spread out in a vertical pattern parallel to the slit(s)?

This has already been asked: https://www.physicsforums.com/showthread.php?t=77835 It is a simple question but I am confused, if the slit or the slits are vertical the direction of the pattern is horizontal or vertical? Vertical: | | |...

Thank you PAllen I saw that somewhere but did not know it was only light related, I guess the phenomenon It is not the same since one has transverse doppler and the other one does not. Let me look at it and see what is about.

When I ask for differences I am not meaning mathematical ones since that it is obvious: We have a phenomenon p, p can be described by Galilean Relativity (GR) and by Einstein Relativity (ER). ER(p)!=GR(p) The math expression that describes this phenomenon is different. Then the doppler...

Thanks ghwell maybe I have explained bad myself, I know light travels at different speeds in different mediumd due to the refractive index but what I wanted to know is if light is affected without changing the refractive index? Let's see if I explain it correctly suppose that light is traveling...

I am not able to understand light although I guess I am not the only one since It is such an abstract subject. When light with its own duality wave-particle goes through the air, does it experiment any collision against it? Because air must have particles, atoms... should not there be a...
