WebApr 5, 2024 · Because the refractive index of LYSO (1.82) is significantly larger than this value, reflection from the edges of the scintillator are strong (note the critical angle of 54°). The photons exiting the scintillator and the lightguide on the lateral surfaces are considered absorbed. Thus, 100% absorption inside the paint is assumed. WebThe refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v. It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam. nuclear war near misses https://pipermina.com
