SUMMARY
The discussion clarifies that the amplitude of light is not halved after passing through a polarizer; instead, the focus should be on irradiance. When natural light with a flux density I0 passes through HN-38 and then HN-32, which is oriented at a 30-degree angle to the first, the irradiance after the second polarizer will be less than half of the incident light due to the properties of real polarizers. The ideal assumption of halving the amplitude applies only to theoretical scenarios, not practical applications involving specific polarizing materials.
