Blue Sky Reason
After all, why the color of the sky is not red or yellow, know the science of blue.
The question that often arises in your mind is why the color of the sky is blue instead of red, yellow or any other color, you must be looking for an answer. But here you can get answer to your question in an easy way.
Wherever you look, the sky looks blue. The question is why it doesn't appear to be any other color entirely. Whether you are in India, Europe or elsewhere. Be it fields, deserts or forests, the color of the sky is blue everywhere. This question may bother you. Many questions are swirling in the minds of the students about why this happened. Actually there is no other reason behind it. Only physics can answer that. So here we will try to understand why the sky is blue.
This is the reason, why the color of the sky is not red or yellow
We see blue in the sky just above us. For this, it is important to understand how sunlight interacts with Earth's atmosphere. The visible light spectrum, i.e. the colors we can see, has a total of seven colors from red light to violet. National Weather Service meteorologist Mark Chenard told Live Science that when all the colors mix together, the light appears white. But once the white light from the sun reaches Earth, some of the colors begin to interact with molecules in the atmosphere.
Correlation of color with wavelength
Each color has a different wavelength in the spectrum. It means how far a color travels. For example, red and orange light waves have long wavelengths while blue and violet light waves have very short wavelengths. Light has shorter wavelengths that are scattered or absorbed by air and gas molecules in Earth's atmosphere, making them more likely to be re-emitted in the other direction. Molecules in the atmosphere, primarily nitrogen and oxygen, scatter blue and violet light in all directions through a phenomenon called Rayleigh scattering. This is what makes the sky blue.
