H2-22: INTERFERENCE - TRANSPARENCIES
Additional Info
- ID Code: H2-22
- Purpose: An optical analog to the interference pattern from two identical sound sources.
- Description: Transparencies consisting of a series of equally-spaced concentric rings are superimposed on each other. The interference pattern from these two identical sources can be observed as the distance between the two sources is varied. Two sizes of circle spacings (corresponding to two wavelengths) are supplied, as shown in the photographs.
- Availability: Available
- References: REFERENCES: (PIRA 3B50.40)
- Loc codes: H2
