Relative refractive index


  • Webster's Revised Unabridged Dictionary
    • Relative refractive index (Opt) the ratio of the sine of the angle of incidence to the sine of the angle of refraction for a ray passing out of one of the media into the other.

In science:

R(λ, z ) = (nλ − 1) tan z where nλ is the refractive index of the atmosphere at wavelength λ relative to the vacuum and z is again the zenith angle (Green 1985).
Positioning errors and efficiency in fiber spectrographs
Lambert & Rickett (2000) looked at the correlation between the modulation index for long-term variations from refraction and the relative decorrelation bandwidth, δνd/ν , which comes from diffraction.
Interstellar Turbulence II: Implications and Effects
From the lack of energy of the G field, the new kind linear black hole (LBH) would be a giant nucleus around which the high gradient of the relative refraction index would prevent, by critical reflection, the escape of radiation and relativistic particles.
Critical Tests for two Hypotheses used in Gravitation and Cosmology
Refractive index is then related to its sources and the sources tensor is defined.
Can physics laws be derived from monogenic functions?
Electromagnetism and electrodynamics are formulated as particular cases of refractive index in section seven and the sources tensor is here related to a current vector.
Can physics laws be derived from monogenic functions?
Liouville-string models of space-time foam motivate corrections to the usual relativistic dispersion relations that are first order in the particle energies and that correspond to a vacuum refractive index η = 1 − (E /MPl)α , where α = 1.
Lorentz Violation: Motivation and new constraints
It gives a physical interpretation of a varying vacuum refractive index equivalent to the curved spacetime in General Relativity.
Does the speed of light depend upon the vacuum ?
With η = 1/3, one obtains the right expression of the vacuum refractive index as derived from general relativity and given in Equation (32).
Does the speed of light depend upon the vacuum ?
This physical interpretation of a varying vacuum refractive index analogy to General Relativity do bring constraints on the way inertial masses should depend upon the vacuum.

Mini-Proceedings ECT*: Speakable in quantum mechanics: atomic, nuclear and subnuclear physics tests
Cherenkov detection produces relatively little light compared with that produced by scintillator (by approximately a factor of 50) and has the disadvantage that particles must have speeds exceeding c/n to be visible (here, n is the index of refraction of the material).
Supernova Neutrino Detection
Also included are measurements derived from the “average” n(z) values obtained using absolute t0 measurements, as well as comparisons with the predictions of the Schytt model , which relates index of refraction directly to firn density ρ(z ), assuming that the ice-firn transition occurs at either z=-115 m or z=-130 m.
Recent Results from the RICE Experiment at the South Pole
The value of this is quite arbitrary, and hence one cannot provide a useful limit. A related effect of Vs would be to modify the refractive index of UCN’s in a material.
A Limit on Short-range Modifications to Gravity
The constant phase φ [related to the amplitude of the linear refractive index at the interface (at x = 0)] plays a nontrivial role in the form of the effective potential and the corresponding soliton statics and dynamics in the structure.
Reflection, Transmission and Trapping Dynamics of Lattice Solitons at Interfaces
Let us address the relatively simple case in which a given signal φ can be represented by an aggregate of monochromatic waves, all of them traveling along the same direction, and in a dispersive medium characterized by a refractive index, n = n(ω ), depending on the frequency.
