Web27. Sept. 2024 · Mystery surrounds strange parallel lines spotted in the sky over Yorkshire. Residents in the West Yorkshire village of Marsden reported seeing a trail of faint white lines - with several rows crossing over - from around 9pm on Sunday. The strong wavelength dependence of the scattering (~λ ) means that shorter (blue) wavelengths are scattered more strongly than longer (red) wavelengths. This results in the indirect blue light coming from all regions of the sky. Rayleigh scattering is a good approximation of the manner in which light scattering occurs within various media for which scattering particles have a small size (p…
