comment What does electric field of unpolarized light look like when measured?
''In practice you don't get fields that classically fluctuate very fast since sources can't produce that light.'' This is incorrect. Most ordinary light is unpolarized, which is possible only with fast fluctuations. Nonfluctuating sources can produce completely polarized light only.
