Hi I'm stuck on a conceptual question I am working on which has frustrated me as I'm not sure I still understand this topic but essentially the question is asking:
You complete a Youngs double slit experiment and observe a good interference pattern. Out of curiosity you now use two separate light sources instead of one to illuminate the double slit. Would you observe any changes to the intereference pattern and explain why ?
I think the two light sources would have no phase relation with eachother so there would be no visible interference because they do not interfere. I don't know if this is right though and would prefer a better explanation.
Thank you for any help
