Describes an experimental arrangement which provides a simple introduction to holographic interferometry. (SL)

Presents simple and inexpensive demonstrations of properties of metallic glasses. (SL)

Using the simple optical system and photodiode described in this article it is possible to give clear, quantitative demonstrations of all the Fraunhofer diffraction phenomena at single and multiple apertures. These measurements can be related to the theoretical predictions given in standard textbooks. Circuit diagram and optical layout are…
