SPECTRUM OF LIGHT KIT: Visible

SPECTRUM OF LIGHT KIT: Visible

•  This Spectrum Of Light Kit is used with an OHP to display, describe and allow discussion on the visible light spectrum and the role of various coloured filters without requiring mathematical calculations.
•  A continuous reference spectrum is projected on the OHP screen with the spectrum of the two colour filters in the form of gels being viewed as well. (i.e the yellow gel overlapping a blue gel is green gives a yellow).
•  Kit comprises :
-  Large piece of holographic diffraction grating
-  Slit for the OHP stage
-  30x colored gels (approx.)
-  3x Special flasks for viewing the transparent colored liquid.

(Wikipedia excerpt: .."...A spectrum (pl.: spectra or spectrums) is a set of related ideas, objects, or properties whose features overlap such that they blend to form a continuum.[1] The word spectrum was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism. In the optical spectrum, light wavelength is viewed as continuous, and spectral colors are seen to blend into one another smoothly when organized in order of their corresponding wavelengths. As scientific understanding of light advanced, the term came to apply to the entire electromagnetic spectrum, including radiation not visible to the human eye. . ....")
