World's Most Asked Questions Why is the Sky Blue

The video explores why the sky appears blue, focusing on Rayleigh scattering, which causes shorter blue wavelengths to scatter more than red. Although violet light scatters more, human eyes are more sensitive to blue, explaining why the sky isn't purple. The video also touches on color preferences and how some animals perceive colors differently.

What are the three main factors that contribute to the sky appearing blue?

• Sunlight, atmospheric particles, and human perception

• Sunlight, water droplets, and dust

• Sunlight, clouds, and human perception

• Sunlight, rain, and atmospheric pressure

Which molecules in the atmosphere are primarily responsible for scattering blue light?

• Oxygen and nitrogen

• Water vapor and ozone

• Argon and helium

• Carbon dioxide and methane

What is the name of the effect that causes blue light to scatter more than red light?

• Thomson scattering

• Compton scattering

• Rayleigh scattering

• Mie scattering

Why do humans perceive the sky as blue instead of violet?

• Violet light is blocked by clouds

• Human eyes are more sensitive to blue light

• Violet light is absorbed by the ozone layer

• Blue light is more abundant in the atmosphere

Which color was reported as the least favorite in the survey mentioned?

• Yellow

• Green

• Purple

• Red
