Admin Why is the sky blue but space is dark?
Since you see blue light from everywhere overhead, the sky looks blue. In space, there is no air. Because there is nothing for the light to bounce off, it just goes straight. None of the light gets scattered, and the “sky” looks dark and black.
Why is the sky blue for adults?
Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Why do we never fall off the earth?
A force called gravity is pulling you down towards the centre of the Earth. Anything with mass also has gravity, the more mass something has, the stronger the pull of gravity. So we don’t fall off the Earth at the South Pole because gravity is pulling us down towards the centre of the Earth.
Why are swimming pools blue?
Pool water is dyed blue by the chemicals used to keep it healthy. Chlorine is added to pools to keep the water clear. It’s also important to point out that salt water pools, which use salt chlorine generators are just as healthy and just as clear as those using traditional chlorine.
What is the reason for the sky being blue?
The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere. This scattering, called Rayleigh scattering, is more effective at short wavelengths (the blue end of the visible spectrum).
What makes the sky look blue?
Modern science and the 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, using the light from the sun and the particles of Earth’s atmosphere.
Is the sky blue because the sea is blue?
Why is the sky blue? The sea and other water bodies are large masses of water contained by catchments in the land whereas the sky is all around us. Even the sky, like the sea appears to be many different shades of blue. You can make this comparison because the same effect that takes place in the sea is what makes the sky blue.
Is the sky really a blue color?
Sky blue is a series of colors inspired by daytime sky. The sky is blue due to a process known as Rayleigh scattering whereby the small particles in the Earth’s atmosphere scatter short wavelengths of blue light more efficiently than longer wavelengths of visible light such as red.
