why is the sky blue?

Answer 1

The color of the spectrum is V I B G Y O R. The B (blue) is visible when it is scattered by the air in the atmosphere during cloudless daylight. The sky is black at night.

Answer 2

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light with a wavelength of about 720 nm, to violet with a wavelength of about 380 nm, with orange, yellow, green, blue and indigo between. The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.

Answer 3

the sky is blue because it has so many gas forms in the sky plus the suns light rays hitting the atmosphere that they create a blueish affect

Answer 4

The process is called Rayleigh scattering. Upallnight has described the process.
