How polarization of light can be demonstrated on a parallel arrangements of crystals explain?

When light passes through a parallel arrangement of crystals, such as a polarizer-analyzer pair, the crystals filter the light waves based on their orientation. If the crystals are aligned parallel to each other, they allow light waves oscillating in a single plane (polarized light) to pass through while blocking the waves oscillating in other planes. This demonstrates the polarization of light, as only light waves vibrating in a specific direction can transmit through the arrangement.
