Question

why does the sky appear in blue colour​

Answer 1

Answer:

Hi there!

The solar rays received from sun vobtains the seven colours of spectrum. These lights of different colours refract at different angles due to the atmosphere. The red light refracts the least due to its long wavelength and it directly crosses the atmosphere without reaching the earth's surface. The blue light is refracted to a higher extent bh the atmosphere and reaches our eye. Thus, the sky appears blue to us.

Answer 2

Answer:

Sky appears blue during day:

Our atmosphere is consist of gases (Nitrogen and Oxygen) , dust particles and other microscopic particles. When polychromatic sunlight enters in to the atmosphere it is absorbed by the above mentioned particles and again remitted.

But according to Rayleigh's law of scattering of light the intensity of the scattering of light is inversely proportional to the wavelength of light.[I ∝1/λ]

So lightrays with smaller wavelength like blue and violet are scattered most.

but due to the presence of blue ray in greater proportion in white ray (sunray) sky appears blue.

Let me know, how is my explanation....
