¿Por qué el cielo es azul?

The video explains why the sky appears blue on Earth due to Rayleigh scattering, a phenomenon where shorter wavelengths like blue and violet are scattered by small molecules in the atmosphere. It contrasts this with the black sky seen from the Moon. The video also discusses the composition of white light, the visibility of different colors at sunset, and how clouds appear white or dark based on their density. Finally, it encourages viewers to share and subscribe for more content.

Why does the sky appear blue on Earth but black on the moon?

• Because the moon has a different gravitational pull.

• Because the moon is closer to the sun.

• Because the moon has no atmosphere to scatter light.

• Because the moon reflects more light.

What is the primary reason blue light is scattered more than red light in Earth's atmosphere?

• Blue light is absorbed by the atmosphere.

• Blue light is more intense.

• Blue light has a shorter wavelength.

• Blue light has a longer wavelength.

Why is violet light less visible to the human eye compared to blue light?

• Violet light is absorbed by the atmosphere.

• The human eye is less sensitive to violet light.

• Violet light is not scattered.

• Violet light is too bright.

During sunset, why do we see more orange and red colors in the sky?

• Because the sun is closer to the Earth.

• Because blue light is scattered out of view.

• Because the sun emits more red light at sunset.

• Because the atmosphere is thinner.

What causes clouds to appear white?

• Clouds only reflect blue light.

• Clouds are made of white particles.

• Clouds reflect all colors of light equally.

• Clouds absorb all colors of light.
