WebIncoherent vs. Coherent scattering Structural colours of avian tissues are produced by light scattering from the interfaces between structures of different refractive indices. The observed colour of a tissue is the result of scattering by numerous scattering structures in the tissue which comprise planes or arrays in the tissues. WebSince the scattered x-ray photon has less energy, it, therefore, has a longer wavelength than the incident photon. The event is also known as incoherent scattering because the photon energy change resulting from an interaction is not always orderly and consistent.
