TL;DR: The general law of reflection as mentioned in this paper is derived from the extremum principle for propagation of variable-frequency light rays and the compatibility of the general law and the special relativistic treatment of reflection is examined in detail.
Abstract: The general law of reflection concerns situations when the light ray undergoes a shift of frequency at the reflection point. For example, it governs reflection of light rays from a moving mirror (either in a vacuum or in a transparent medium), reflection from a motionless mirror coated with a layer of Raman-active molecules in the coherent-scattering regime, or external reflection of X-rays from the surface of a condensed matter sample, with partial dissipation of energy within the skin depth. The general law of reflection is derived from the extremum principle for propagation of variable-frequency light rays. It states that the angle of reflection depends not only on the angle of incidence but also on the frequency shift in the reflection point and dispersion of the refractive index of the medium in contact with the mirror. The compatibility of the general law of reflection and the special relativistic treatment of reflection is examined in detail. Applications of the new law of reflection are discussed ...

TL;DR: In this paper, the reflection and refraction of a plane sound wave by a nonequilibrium relaxing medium are examined, and Snell's law of refraction is modified depending not only on the properties of the media, but also on the angle of incidence.
Abstract: The reflection and refraction of a plane sound wave by a nonequilibrium relaxing medium are examined. Since the medium is dissipative, Snell's law of refraction is modified depending not only on the properties of the media, but also on the angle of incidence. The amplitudes of the reflected and refracted waves are complex. Variations of both the angle and amplitude are analyzed and supplemented with calculations for different reaction rates and relative Mach numbers.

TL;DR: In this article, the effect of total external reflection from an anisotropic crystal in the anomalous dispersion region is calculated for hexagonal BN crystal near the boron K absorption edge.
Abstract: A new method of development of x-ray polaroids is suggested. The idea is based on the effect of total external reflection from an anisotropic crystal in the anomalous-dispersion region. The polarization coefficient for hexagonal BN crystal near the boron K absorption edge is calculated for different glancing angles and thicknesses of sample. It is shown that the method treated provides a simple way of constructing an effective x-ray polaroid.
