This reduced scattering allows red light to travel longer distances without being dispersed, making it more prominent during sunsets and sunrises.

Reduced Rayleigh Scattering: Rayleigh scattering is a type of scattering that occurs when light interacts with particles that are much smaller than the wavelength of light. Blue and violet light undergo significant Rayleigh scattering due to their shorter wavelengths, causing them to be scattered away in all directions. Red light, with its longer wavelength, experiences less Rayleigh scattering, allowing it to travel in a more direct path.
Mie Scattering: Mie scattering is another type of scattering that occurs when light interacts with particles that are comparable in size to the wavelength of light. In the atmosphere, aerosols and dust particles can cause Mie scattering. While blue and violet light are more susceptible to Mie scattering, red light is less affected, enabling it to penetrate through these particles more effectively.
Longer Wavelength, Less Scattering: The inverse relationship between wavelength and scattering means that longer wavelength light experiences less overall scattering. This is a fundamental property of electromagnetic waves and explains why red light, with the longest wavelength in the visible spectrum, is less susceptible to scattering and can travel longer distances.

In summary, the reduced scattering of red light in the atmosphere allows it to propagate over greater distances without significant dispersion. This property contributes to the observed prominence of red light during sunsets and sunrises, when the sunlight has to travel through more of the atmosphere to reach our eyes, resulting in the scattering of shorter wavelength colors and the dominance of longer wavelength red light.
