Why is the sky blue

When someone walks out of the house and then raises his head up into the sky then sees how far the sky is on a clear day, the eyes will catch the blue that dominates the sky. Why is the sky blue, what is the cause? Maybe you and I also feel that, one question that we might ask during childhood, however, maybe we haven't remembered the explanation, even though our teacher when explaining the lesson explained it.

Based on the background or question above that has occurred in our hearts, experts answer that the blue sky is caused by the interaction of the atmosphere and sunlight. White light, including sunlight, is made of light particles of different colors. Each has a wavelength that corresponds to the celestial bodies in the vicinity. Then some different things can happen when the light comes into contact with substances or interactions with the sun's own light.

One example that often happens, when sunlight penetrates transparent objects like water, waves of light will be refracted or curved. Because light changes its speed while moving from one medium (air) to another medium (water) so that the effects of sunlight reflect and emit light that is different from the original. So don't be surprised if the sky is blue or changes to another color.
