Describing light or waves that do not have a specific direction of vibration or orientation.
The unpolarized light passed through the lens without any change in its properties.
Unpolarized → It is formed from "un-" (meaning not) and "polarized" (from "polar" which comes from Latin "polaris", meaning of the poles). The word "unpolarized" means not having distinct poles or not exhibiting polarization.
Think of 'not' ('un-') having distinct 'poles' ('polar') — that's why unpolarized means lacking distinct poles.
