Abstract

Interference taking place when a parallel beam of monochromatic light is incident normally on a wedge interferometer, with highly reflecting surfaces enclosing a refracting medium is studied theoretically. The theory predicts the presence of a number of planes of localization other than the Feussner plane of fringe localization of zero order close to the wedge. Brossel’s formula giving Feussner surfaces of high orders is a special case when the refractive index of the enclosed medium equals unity. The derived formula is verified experimentally. The refractive index of the enclosed medium is determined by measuring the fringe separation and the distance between any two successive planes of localization.
