WebApr 16, 2015 · 4. No, Rayleigh scattering models the probability (and angle) of scattering as a function of wavelength and of the particle sizes. All wavelengths travel a long way but the path followed (scatter or nonscatter) varies. Since space is mostly "empty", there's little scattering. Beyond that, your understanding of stars is quite incomplete. WebRayleigh scattering also produces red sunsets. When the sun is low on the horizon, the solar beam travels a slanted, longer path through the atmosphere. By the time the beam reaches your eye, the intensity of blue and green light is greatly diminished by scattering, leaving a dominant red color.

Scattering and/ or absorption of light is responsible for many phenomena such as red sunsets.

WebThis is because of a phenomenon known as Rayleigh scattering, where molecules in the Earth’s atmosphere scatter sunlight in all directions, and blue light is scattered more than other colors, making the sky appear blue.
