Rainbow Symphony Color Paddles Set with Diffraction Gratings

Color Paddle Set Contains: Primary Mixing Colors (3) RED, BLUE, GREEN. Secondary Colors (3) CYAN, YELLOW, MAGENTA. Diffraction Grating (1) 13,500 Line / Inch Double Axis (1) 500 Line / mm Single Axis. Polarized Filters (2) Polarizing Filters. Diffusing Filter (1) 3/8 White Filter - 63% Transmission. Mixing Primary and Secondary Color Paddles are used for experiments involving additive and subtractive color, color mixing, color transmission, absorption and filtering of the different wavelengths of light. Diffraction Gratings are used for the direct viewing and analysis of spectra from different light sources. Experiment with both the 13,500 line/inch and the 500 Line/mm. The diffraction gratings are the principal component in a spectroscope and can be used for many of the same experiments. View the spectra from different gas tubes. Polarizing Filters are used for experiments involving birefringence, light scattering, polarized filter experiments, light reflection, Brewster's angle, how polarized sunglasses work and much more!
