Optics v number

WebFor step-index single-mode fibers, the mode radius may be estimated from the core radius a and the V number, using Marcuse's equation [1]: This shows that the mode radius becomes smaller for higher frequencies, which have higher V values. The equation is fairly accurate for V values above 1. WebWave numbers and wave vectors play an essential role in optics and the physics of wave scattering, such as X-ray diffraction, neutron diffraction, electron diffraction, and elementary particle physics. For quantum mechanical waves, the wavenumber multiplied by the reduced Planck's constant is the canonical momentum .
