N3-25: SERIES RED FILTERS

ID Code: N3-25
Purpose: Show saturation using series filters.
Description: A series of red filters is arranged so that light can be seen as it emerges from each successive filter. (Each square filter in the series occupies less of the area of the first filter.) Pass light through the filters or look at a white light through the filters to see how saturation changes the color.
