چکیده انگلیسی:Measuring the refractive index n of a substance or medium is part of every introductory
physics lab. Various approaches to determine this index have been developed over the
years based on the different ways light reflects and transmits in the medium.
With the introduction of lasers in basic physics courses, a number of these methods
have become accessible to the undergraduate physics laboratory. Several of these
techniques are highly accurate and use specific optical equipment, like spectrometers,
interferometers, or microscopes. In the laboratory, the method instructors choose to
measure the refractive index of a liquid depends on different factors, such as the optical
properties of the substance they want to study, or simply the resources available at
hand, that in many cases, are very limited.
Among all those different methods, the spherical concave mirror filled with a
liquid makes itself an excellent alternative to measure the refractive index of the liquid,
specially when no fancy apparatuses are available, and the accuracy of the measurements
is not critical.
In this paper, we would like to present a simple geometrical derivation of the
refractive index of a transparent liquid that is obtained using a spherical concave mirror.
This derivation relies mostly on Snell’s law and the small-angle approximation. In
addition, we also use Gaussian optics equations for mirrors and thin-lenses to verify the
validity of the refractive index equation.
چکیده فارسی: این مقاله، روش آینه مقعر کروی برای اندازه گیری ضریب شکست مایعات شفاف را توصیف می نماید. ما، معادله ضریب شکست را با استفاده از قانون اسنل و تقریب زاویه کوچک به دست آوردیم. ما درستی این روش را با استفاده از آینه کروی مرسوم و معادلات گائوسی عدسی نازک بررسی نمودیم.
