WebRayleigh scattering (/ ˈ r eɪ l i / RAY-lee), named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering particle … WebRayleigh scattering, dispersion of electromagnetic radiation by particles that have a radius less than approximately 110 the wavelength of the radiation. The process has been named in honour of Lord Rayleigh, who in 1871 …
WebThe difference between the two is based on the definition that both Abbe and Rayleigh used in their derivation for what is meant by two objects being resolvable from each other. In practical applications, this difference is small. The Abbe criterion is defined as: while the Rayleigh criterion defines the resolution mathematically as: WebAlthough the Rayleigh criterion and similar measures are useful resolution gauges for observation of the specimen, there remain several shortcomings of such a definition for resolution. For example, in cases where the investigator is aware that two particles are merged to form a single point image, computer algorithms can be applied to discriminate …
