What causes the sky to look blue?
One of the eternal questions that have long been not answered by ideas is what causes the sky to look blue. Modern science and understanding of light waves have provided an answer, although many false answers are still popular. What causes the sky to look blue is the result of electromagnetic scattering by means of light from the Sun and the particles of the Earth's atmosphere.
If you want to understand what causes the sky to look blue, you need to understand how light waves work. The light wave is a vibrating field of energy that travels in the waves. The distance from one wave to the other is called the wavelength and determines the color of the light. The light from the sun contains all different colors; They all mix together and create white light that travels in a straight line until it hit anything. Depending on the object in which it encounters, light can be divided into different lengths of light waves. The shortest light waves correspond to blue and purple colors that also have as much Conained Energy and the highest FRequation.
When a light wave hits a particle of gas, such as those that make up the atmosphere surrounding the ground, the particles can absorb part of the wave energy. Regardless of the energy that the particles absorb, radiate or reflect. Because they have the highest frequency, the waves of blue light are more often absorbed than their slower, less energy companions.
Rayleigh Scatting, a process named after an English scientist who discovered it, describes what causes the sky to look blue. Due to microscopic textures on the surfaces of the atmosphere particles, the blue absorbed light is not only emitted or reflected in one direction, but shoots in a variety of directions. When you look at the sky, you see scattered light as it bounces throughout the atmosphere.
Rayleigh dispersion also describes why the sky in Col lightens towards the horizon seems to be. Because you look at the sky much further, the waves withBranches pass through more air to get to you. The farther you look, the less concentrated the scattering becomes, causing lighter blue shades near the edge of the horizon.
If you are wondering why the sky red and orange at the sunrise or sunset, it is also a scattering process. When the sun is near the horizon, it must go through a much more atmosphere. Just as he does, longer light waves that pass through the thinner layers of the atmosphere, are the only waves that distract completely dispersed. Longer light waves form orange and red in color, so it is the light that becomes visible in the east and sunset.
Popular false explanations suggest that the sky is blue because the light is reflected from the blue oceans. In fact, it works the other way around. What causes the ocean to look blue, is the same thing that causes the sky to look blue. Ocean is reflective -gig color of the sky so if the sky is scattered blue light, the particles in the ocean receive and disperse the majorityinou blue light.
