We have come to know that the color of the sky is blue. At night the dark blue is almost black, but blue in the daytime. This blue of sky is so true that blue is also called the sky color.

• Have we ever wondered why the sky is blue ?

• Who's blue coloring to the sky !

Before understand the reason of blue sky, let's do a simple scientific experiment.

This test name, soap water and white light test. Let's see what we need to do to check that at the beginning---

• A long water pot
• Water
• A little white soap, or milk, or white color
• White LED lights

How to do:

• The water in a glass of water with a little soap, milk or white color will be light but transparent white color. The atmosphere that surrounds the earth's terrain is also like this, transparent-white.
• The light of the white LED lights will have to be passed through the glass by darkening the house.
• Now the glass brings to the right angle with a little shuffle, the color of the glass of water will become blue.

Why happened to this ?

It is very important to know some things before understanding why this incident happened. For example, what is in the white light. There is no light in white light. The light is actually seven colors. These are violet, blue, sky color(light blue), green, yellow, orange and red. The truth is that these seven colors are not true. The basic color is actually three. Red, green and blue The rest of the colors are due to these three colors. When all the colors are mixed then the color of the light is white.

We got this white light from the LED light. The same white light comes from the sun to earth.

When the light enters the Earth through the atmosphere, the blue light is the most scattered when passing through a white translucent atmosphere. As a result, we can only see the blue color standing on the surface.

The white color we have in our experiments in the water has transformed the water into a white translucent, just like the atmosphere. The difference is that there are dust particles in the atmosphere that disperse white light and our solution uses soap or milk molecules or white molecules.

This simple scientific explanation is the only reason why the sky is blue.
