![]() ![]() Here is a link to show the differences between Rayleigh Scattering and Mie Scattering as particles become larger in size. Larger particles (outside the Rayleigh limit) should scatter more light in the forward direction, as in the Rayleigh-Debye graph, which shows that the form factor introduced in Equation is necessary to predict the scattering intensity of larger particles. While the Rayleigh-Debye predicted scattering intensity occurs mainly in the forward direction. The same particle sizes and wavelengths were used as in the Rayleigh scattering graph above.Īs you can seen in the graphs above the Rayleigh predicted scattering intensity is the same for forward and back scattering. Polar Plot depicting the Rayleigh-Debye Relative Scattering Intensity for scattering angles from 0 to 360 degrees. The particle sizes used were 50, 60, 70, 80, 90, 100 nanometers in diameter. The wavelength used was 400 nm or violet light in the visible spectrum since this is the shortest wavelength in the visible spectrum and as a result has the smallest Rayleigh limit. Polar plot depicting the Rayleigh Relative Scattering Intensity for scattering angles from 0 to 360 degrees for Particle Sizes larger than the Rayleigh limit ![]() For my project I also wanted to look at the Rayleigh predicted scattering intensity for a particle size larger than the Rayleigh limit and compare that to the Rayleigh-Debye predicted scattering intensity. ![]()
