The phenomenon is called birefringence…
Which is just the different between refractive indices for light polarized in different directions. When polarized light passes through certain materials or films, it is split into two components that travel at different speeds, causing phase shifts and interference…. This is the rainbow-like colors that you’ll see with polarized glasses on.
Alternatively, wearing s polarized glasses and viewing a screen that has a p polarized film, will block the light… Why? Because it’s orthogonal….
