Question

Why is the sky blue?​

Answer 1

Answer:

The blue color of the sky is due to the scattering of air molecules in the atmosphere.

Explanation:

The blue color of the sky is due to the scattering of tiny air molecules. White light is passing through the atmosphere in the daytime. The wavelength of the white light decreases when the scattering of these air molecules increases. So the sky appears in blue during the daytime.

Answer 2

• Because air molecules scatter blue light from the sun more than red light, a clean cloudless daytime sky is blue.
• Because the blue light has been spread out and away from the line of sight, when we look towards the sun at sunset, we see red and orange colours.
• The sun's white light is a kaleidoscope of rainbow colours. Isaac Newton showed this by separating the different colours with a prism to make a spectrum.
• The varied wavelengths of light differentiate the various colours.
• Between red light with a wavelength of about 720 nm to violet light with a wavelength of about 380 nm, the visible section of the spectrum includes orange, yellow, green, blue, and indigo.
