Lets take a laser beam, split it into 2 beams, pass one through vacuum and the other one through a gas filled tube, and then recombine them and you get a combination of 2 identical laser beams with different phases, and that I've managed to do in a lab. I indeed got an interference pattern due...
Hello fellow physicists :)
I have the following question:
take a beam of light traveling in some direction x, let's use lasers due to their coherency and monochromatic properties.
Now let's take another nearly identical beam traveling in the same direction x, only that it's 180° in phase with...
