Describe an interference wedge and elaborate briefly as to where they are used.
An interference wedge is a technique used for interference in spectroscopy. A light from the source (S) is located at the focal point of a Fresnel lens (F1), and focused by a second lens (F2) to form a real image S' of S at the aperture of the integrating sphere (IS). The LCD is mounted in the collimated beam directly after the interference wedge (IF) which gives ...
The solution explains what an interface wedge is as well as providing information as to how it can be used in the field of spectroscopy and a diagram showing details clearly.
