Watch it come to life
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!
We've been ordering from you for more than a decade and love your products. Thank you for the may ways you share your bounty of filters with us - colors, diffraction, solar viewing - you name it. Glad to work with you all always. Keep up the great work.
Lots of intel here. Great for small groups of children.
