An interferometer has been used to measure the change in index of refraction with change in pressure or temperature. Absolute indices of refraction are reported to five decimals for benzene, carbon tetrachloride, and water at eight different...
A method is presented for analyzing the temperature intervals of the NBS (1955) temperature scale and the International Practical Temperature Scale (IPTS). Values of dT/dR as a function of resistance are derived from equations of dQ/dR and dQ/dT,...
