WIth an oscilloscope that records all the data, you could look at the graphs and detect it. But human ears, it would sound exactly the same.
>>11591526Light can only have longitudinal components inside of a material, where its being renormalized by the material permitivity. The only reason we even call that "light" is because we are too lazy to make a new name for it.
Its the equivalent of saying empty space is positively charged because holes exist in semiconductors. No, that's an emergent property of the material when empty space is present inside the material.
