Answer:
The sky is blue because gases and other particles in Earth's atmosphere scatter sunlight in all directions, which makes blue light scatter the most is its wavelength. The wavelength of blue light is shorter and smaller. This is the reason we see blue sky.
Explanation:
The light emitted by the sun is white light which constitute of all the rainbow colors. The light that is visible to our eyes depends on its wavelength. The light travels in a straight path until and unless it is hindered by some object or particles.
So, when white light from the Sun enters the atmosphere of the Earth, blue and violet light, which are smaller and shorter in wavelength, remains unscattered in the sky. Since blue is the color to which our eyes are mosts sensitive, the sky appears blue to the sky.
