Rayleigh scattering pattern
WebHere we find new patterns in these envelopes when the scattered intensity is normalized to the Rayleigh differential cross section. Mie scattering is found to be similar to Rayleigh scattering when ρ < 1 and follows simple patterns for ρ > 1, which evolve predictably as a function of ρ. These patterns allow us to present a unifying picture ... WebThe observation of right angle Rayleigh scattering from defects in quartz using an argon laser beam which is propagated at 90° to the optic axis is reported. The intensity of the scattered light varies periodically along the axis of the laser beam, which variation is resolved by viewing the scattering regions with a microscope. The visibility of the …
