The sky is blue in colour to the human eye as the short waves of blue light are scattered more than the other colours.
In the spectrum, making the blue light more visible.
Why sky is blue in colour ?When sunlight enters the atmosphere of Earth, all the gases and airborne particles scatter it in all directions.
The phenomenon of light scattering –When the size of the scattering item (like air molecules) is extremely small compared to the wavelength of light, scattering of light occurs.
Inversely proportional to 4 is the quantity of scattering, according to Rayleigh’s equation of scattering.
Different wavelengths are scattered in different ways.
Rayleigh’s law of scattering -Since the wavelength of blue light is roughly half that of red light, blue light scatters about 24 times more than red light.
As a result, the sky appears blue and the colour blue dominates.
