Description

Mix primary (red, blue & green) and secondary (cyan, yellow & magenta) filters to study additive and subtractive color mixing, color transmission, and absorption of different wavelengths of light. Polarizing filters can be used to show birefringence, light scattering, and light reflection. Diffraction gratings can be used for direct viewing and analysis of spectra from light sources. Included are 13,500 line/inch double axis and the 500 line/mm single axis gratings. Filters are 5.5 x 6.7 cm (2.16" x 2.63")
