Hello, First I would like to say I don't have a formal education in physics but I've dropped everything in order to pursue an education in it. My knowledge is at least high school level and dipping into higher level. Recently I thought of a situation and devised an experiment around it. It was based on a problem, I have attached a .jpeg illustrating the experiment and its premise. Even then I will describe it here, along the reasoning I used. It was inspired by the double slit experiment and the phenomena correlated with it. My greatest interest was in the the actual interference. So I pondered: What if you could create two beams, which are ideally identical in every way (frequency, wavelength, synchronization) and all components are ideal, and they both meet (illustrated in attachment) out of phase and as such "negate" each other, i.e the sum of the E and M fields are 0? When I mean ideal I mean ideal; complete vacuum, etc,. I realize that actually building such an experiment physically might be practically impossible, really this is an issue about the theoretical aspect. I have asked this question to a professor and several grad students and I have only received an, "I don't know.".
