If you test two samples and find that they both produce a red flame, what tool could be used to determine for sure whether they contain the same metal?

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?
