Rayleigh scattering raman scattering
WebApr 11, 2024 · Rayleigh scattering is caused by molecules in solution vibrating at the same frequency as the incident light (first-order Rayleigh), and it also emits light at twice the wavelength of the incident light (second-order Rayleigh). Raman scattering occurs due to the interaction between molecules and incident light. WebThis phenomenon is called elastic or rayleigh or linear scattering, however, the great Indian physician Dr.C.V.Raman observed that the scattering of light has discrete frequencies …
