19 short films which have been transferred from film to videodisc. We have most of these as 8mm film loops. A sound track, written by Professor Miller, has been added. A Teacher's Guide is on file in the Physics Demonstrations Library.
The code, eg 4:40, [*****;W;1], is from the 8mm film loop index.
domain walls on an iron whisker, dependence of domain size and shape on field
16. Paramagnetism of liquid oxygen, 3:40, [***;H,EM;1]
liquid oxygen and nitrogen poured over pole pieces of magnet
17. Absorption spectroscopy, 3:50, [***;O,MP;1]
emission and absorption spectrum of a sodium flame (beautiful), absorption spectra of hemoglobin in solution, didymium glass
18. Radioactive Decay
19. Scintillation spectroscopy, 3:35, [***;MP;?]
assembly of scintillation detector, spectrum of Mn56 for 3 counting times showing photopeak, Compton edge and backscatter, useful for properties of detector and for showing effect of longer counting times
