Final answer:
To minimize glare, keep your windshield clean and use polarizing sunglasses, which filter out polarized light to reduce glare without blocking it entirely. Observing this effect involves rotating the sunglasses and noting changes in reflected light intensity, but never directly look at very bright lights.
Step-by-step explanation:
You can minimize the effects of glare by making sure that your windshield is clean and using polarizing sunglasses. When light is reflected off surfaces such as water or glass, it can become polarized. This means that the light waves vibrate more in one direction than all other directions, which results in glare that can be distracting or blinding.
Polarizing sunglasses work by filtering out a significant amount of this polarized light, reducing glare. The effect can be observed by rotating polarizing sunglasses in front of your eyes while looking at a reflective surface.
You will notice that the intensity of the reflected light changes, becoming brighter or dimmer, although not completely disappearing. When conducting this experiment, always ensure you're not looking directly at very bright light, such as the headlights on your car, to avoid potential damage to your eyes.
