Some measurements on refractive indices
✍ F.W. Heineken; F. Bruin 📂 Article 📅 1954 🏛 Elsevier Science ⚖ 818 KB

A method is described to measure refractive indices of gases at atmospheric pressure and at a frequency of 25,000 Mc/s. The method is based on the change in resonance frequency of a cavity, first filled with a reference gas (nitrogen) and after that with the gas of which the refractive index is to b

Corrections to the indices of community
