Abstract
본 연구에서는 Fabry-Perot 간섭계를 이용하여 산소의 굴절율을 측정하였다. 전체 실험장치는 광원부와 Fabry-Perot 간섭계 및 검출부로 이루어지며 광원은 파장이 5461 A˚인 Hg-lamp를 사용하였고 검출은 X-Y 자동기록계로 하였다. 측정 결과 O_(2)의 굴절율은 1.0002664이었다. 이 값은 국제분광학 회의에서 채택한 값 0℃ 750 mm Hg 에서 1.000272와 비교해 보면 약 0.00055 % 의 오차로 정확한 값이라 볼 수 있다.;In this study I measured precisely the index of refraction of Oxygen gas. Fabry-perot interferometer was assembled with two etalon plate and their holder. Light source and wave length used in determining the reflection index of Oxygen by Fabry-perot interferometer were Hg-Lamp with Hg=5461A˚. When Monochromatic light was projected into F-P interferometer the number of the shifted interfered fringe and their the diameter occuring due to the changes in Oxygen pressure were determined by X-Y recorder. The reflective index of O_(2) were n=1.0002664. Imploying theoretical formula adopted by international spectroscopy council n=l.000272, when Hg 5461A˚ were used as light source and wave length, respectively this figure was equal to the data abtained in this study employing F-P interferometer within a 0.00055% of error.
