These filters are used in various optical experiments and demonstrations. Here are some details about them:

1.      Mounted Color Filter Set (Pack of 6):

o    This set includes three primary and three secondary color filters.

o    The filters are acetate (a type of plastic) and are mounted in plastic frames measuring 50mm x 50mm.

o    While they are not suitable for photographic work, they are robust for general use.

o    The primary filters are: red, blue, and dark green.

o    The secondary filters are: magenta, yellow, and peacock-blue.

o    Each filter allows specific wavelengths of light to pass through, creating a colored effect.

o    Here are the approximate wavelength ranges for each color:

§  Red: 620 - 750nm

§  Orange: 590 - 620nm

§  Yellow: 570 - 590nm

§  Green: 495 - 570nm

§  Blue: 450 - 495nm

§  Indigo: 420 - 450nm

§  Violet: 380 - 450nm

o    These filters are commonly used in educational settings for teaching about light and color.

2.      Raybox Color Filters (Plastic Mounted, Set of 6):

o    Similar to the above set, this one also includes three primary and three secondary color filters.

o    They are acetate filters mounted in plastic frames (50mm x 50mm).

o    Designed specifically for use with the Raybox (code: EDU528).

o    These filters allow students to explore the behavior of light and color.
