Singing this Note is IMPOSSIBLE!

I've heard a lot of voice teachers on youtube explain how resonance in the throat works in relation to singing but i didnt really understand it, but listening to your explanation from a physics perspective I finally understood. I think it's because music theory and professions that study it have their own terminology to explain things at a level that is practical for their field but I can't relate to, whereas using physics terminology I actually did learn in school seems like a deeper level of understanding of the same concept and at the same time ironically more accessible to my understanding it.
