Rayleigh approximation
WebRayleigh absorption cross section are usually derived from electromagnetic oscillator theory in the long-wavelength approximation.7 However, Lord Rayleigh originally de-rived this wavelength dependence with a simple dimen-sional analysis.10 Here, an alternative derivation without the use of electromagnetic theory is presented.
