Hello everyone!
Can anyone explain why sky is blue?
Thanks.

Why is the Sky Blue? Exploring the Science Behind the Color of Our Atmosphere

In summary, sky appears blue because the atmosphere is better at scattering blue light compared to other colors due to Rayleigh scattering. This is a result of the strong wavelength dependence of scattering, which causes blue light to be scattered more readily than red light. Direct radiation from the Sun also contributes to the blue color of the sky.

See Rayleigh scattering in our atmosphere:

The scattered blue light is polarized because of this.

Hello kambez! Welcome to PF!
It's because scattering is inversely prooprotional to the fourth power of wavelength … see http://en.wikipedia.org/wiki/Rayleigh_scattering#Rayleigh_scattering_from_molecules" …

Related to Why is the Sky Blue? Exploring the Science Behind the Color of Our Atmosphere
1. Why is the sky blue?
The sky appears blue because of a phenomenon called Rayleigh scattering. This is when sunlight enters Earth's atmosphere and collides with gas molecules, causing the light to scatter in all directions. Blue light has a shorter wavelength and is scattered more than other colors, making the sky appear blue to our eyes.
2. Does the color of the sky change?
Yes, the color of the sky can change throughout the day. As the sun rises and sets, the angle of the sunlight changes, causing different colors to be scattered in the sky. This is why the sky may appear pink, orange, or red during sunrise and sunset.
3. Why does the sky sometimes appear white or gray?
When there are a lot of water droplets or particles in the atmosphere, the light scatters in all directions and can appear white or gray to our eyes. This is often seen on cloudy or hazy days.
4. Does the sky appear the same color everywhere?
No, the color of the sky can vary depending on location and atmospheric conditions. For example, the sky may appear more vibrant and blue in areas with less pollution and clearer air.
5. Can the color of the sky affect our mood?
Some studies suggest that the color of the sky can have an impact on our mood and emotions. Blue is often associated with feelings of calmness and relaxation, which may explain why many people find looking at the blue sky to be soothing.
