E2-45: ECLIPSING BINARY STAR MODEL - LIGHTS
Additional Info
- ID Code: E2-45
- Purpose: Show how we view a rotating binary star.
- Description: The two bulbs, one with less intensity than the other, are rotated about the axis of the stick. This shows the intensity variation observed for a binary star with two stars of differing brightness.
- Availability: Available
- References: REFERENCES: (PIRA 8B10.10)
