Pourquoi Le Ciel Est-IL Bleu ?
The blue sky has captivated humanity for centuries, but what causes this phenomenon? This article delves into the science behind the blue sky, exploring the intricate processes that lead to this mesmerizing spectacle.
The Science of Light
Understanding the color of the sky begins with comprehending the behavior of light. Sunlight, composed of various wavelengths, interacts with Earth's atmosphere, leading to the scattering of light particles. This scattering phenomenon is central to the blue sky phenomenon.
Rayleigh Scattering
Named after the British scientist Lord Rayleigh, Rayleigh scattering occurs when sunlight collides with atmospheric particles smaller than the wavelength of light. Shorter wavelengths, such as blue and violet, scatter more effectively than longer wavelengths, res...
