Which phenomenon explains why the sky appears blue to the human eye during the day?

دن کے وقت کون سا رجحان اس بات کی وضاحت کرتا ہے کہ آسمان کیوں انسانی آنکھ سے نیلے رنگ کے دکھائی دیتا ہے؟

Polarization of light by the ozone layer

Reflection of sunlight by clouds

Rayleigh scattering of shorter wavelengths of light by atmospheric particles

None of these

Explanation

Rayleigh Scattering: Shorter wavelengths (blue and violet) scatter more than longer wavelengths (red and yellow) due to interactions with atmospheric particles.

Why the Sky Appears Blue: Although violet scatters more, human eyes are more sensitive to blue light, making the sky appear blue.
