¿Por qué se oscurece al mojarlo?

The video explores how wetting affects the color of materials like fabric, sand, and cement. It explains the role of the refractive index in light refraction and reflection, leading to color changes. When materials are dry, light is scattered, giving them a whitish appearance. Wetting introduces a new medium, reducing light scattering and making materials appear darker. The video also discusses scientific theories on this phenomenon, emphasizing the ongoing nature of scientific inquiry.

What happens to the color of clothes when they get wet?

• They remain the same.

• They become transparent.

• They become darker.

• They become lighter.

Which law helps us understand how light deflects when passing through different media?

• Newton's Law

• Snell's Law

• Ohm's Law

• Hooke's Law

What gives snow and beaten egg whites their characteristic white color?

• The presence of air bubbles

• The presence of sugar

• The presence of water

• The presence of salt

How does water affect the refractive index of materials like sand and cement?

• It has no effect on the refractive index.

• It makes the refractive index similar to the material itself.

• It decreases the refractive index significantly.

• It increases the refractive index significantly.

What is the scientific approach towards theories that do not fully align with data?

• They are accepted without question.

• They are ignored.

• They are constantly revised and improved.

• They are immediately discarded.
