Accessories3 lantern slides, two unlabeled, one labeled "Möllenstedt & Düker 2 P. 145 1956 Fresnel Bi-Prism Interferance [sic] w/ Electrons 38
DescriptionThree lantern slides in manila envelopes. One is labeled, the other two are not.
Inside the labeled envelope is a slide labeled "Möllenstedt & Düker 2P. 145 1956 Fresnel Bi-Prism Interference w/ Electrons." A tag on the slide is labeled with a red dot and the number 1518. The slide is a diagram of the Möllenstedt-Düker experiment, which made use of a biprism to separate a spectrum of electron waves to cast interference fringes of electrons on a slide below. This experiment laid the groundwork for electron holography, which was used in electron microscopes. The slide is mounted between two glass panels, the rear of which is broken, all mounted in a black frame.
The two unlabeled envelopes contain polaroid slides of a man dropping a ball. The picture was taken through multiple exposures to demonstrate the acceleration of the ball due to gravity. The slide is mounted in a beige plastic frame, on the bottom of which it reads "Polaroid Slide Mount # 633." In the top right-hand corner of the slide mount is an image of a globe. One slide features a larger ball than the other. On the slide mount for the former, the globe is colored in with a red marker.

Curatorial RemarksThese slides are tagged "meteorology" in the drawer, but they don't really have anything to do with meteorology.
Also present in the description of accessories was the description " 'Quartz Prism(?)' slides," but this did seem to apply.
FunctionSpecific use uncertain, but they might have been used in lectures or presentations.
