What is unpolarized light?

Light that vibrates in all directions perpendicular to its direction of travel.

100

What happens when two polarizing filters are aligned?

Maximum light passes through.

100

Why do we use a model to show polarization?

To visualize how filters control light direction.

200

How does polarized light differ from unpolarized light?

Polarized light vibrates in only one plane, while unpolarized light vibrates in many planes.

200

What happens to light intensity as the second filter is rotated?

Light intensity decreases gradually.

200

What should be included in a good polarization model?

Light source, filters, and clear vibration directions.

300

How can you classify light using vibration direction?

If vibrations are in one plane → polarized; many planes → unpolarized.

300

Why does light disappear when filters are crossed at 90°?

The second filter blocks all vibrations allowed by the first.

300

How does your model relate to real-life applications?

It shows how polarization is used in sunglasses, screens, and cameras.
