This paper describes the spherical concave mirror method for measuring the
index of refraction of transparent liquids. We derived the refractive index
equation using Snell's law and the small-angle approximation. We also verified
the validity of this method using the traditional spherical mirror and
thin-lens Gaussian equations.
