The headlights of a car polarised or unpolarised. Explain.

Explanation

To determine whether the headlights of a car produce polarized or unpolarized light, we can follow these steps:

### Step 1: Understanding Unpolarized Light
Unpolarized light is characterized by the electric field vibrations occurring in multiple directions. This means that the light waves do not have a fixed plane of vibration; instead, they vibrate randomly in various orientations.

### Step 2: Understanding Polarized Light
In contrast, polarized light has its electric field vibrations confined to a specific plane. This means that the light waves oscillate in a single direction or plane, which can be achieved through various methods such as reflection, refraction, or passing through a polarizing filter.
