Scope of this guide
The primary storefront already explains the broad question of how the product makes rainbows. Its Prism Suncatcher FAQ remains the authoritative product overview. This notebook focuses instead on how to document what you see.
Record Four Variables
For each observation, note the sun direction, the approximate prism orientation, the receiving surface, and the ambient light in the room. Change only one variable at a time. This makes photographs from different days easier to compare.
Separate Geometry from Brightness
A spectrum can look longer, wider, sharper, or more saturated for different reasons. Geometry describes where the color lands and how it spreads. Brightness describes how visible it appears against the surrounding surface. Treat those as separate observations rather than assuming one causes the other.
Use Neutral Language
Describe visible results such as “edges appeared sharper on the shaded wall” or “the band shifted when the sun angle changed.” Avoid assigning an exact refractive index, composition, percentage improvement, facet count, or projection limit unless the number is tied to a cited technical source for the exact material and design.
Suggested Field Note
- Date and local time
- Weather and direct-sun conditions
- Room and receiving surface
- Camera settings, if photographed
- One changed variable
- Plain-language result
Background reading: the University of Central Florida's open physics text explains refraction and dispersion in general optical terms. This page does not use that source to infer product-specific measurements.
