Used in these demonstrations

Kodak slide projector with circular slit holder, equilateral plexiglass prism on platform, and white sketch paper on blackboard showing dispersed rainbow spectrum in darkened room

Action of a Prism

Demonstrates dispersion of white light through a prism, showing that refractive index depends on wavelength. Students observe the continuous visible spectrum produced when shorter wavelengths (violet) refract more than longer …

Multiple rainbow spectra projected on paper mounted to blackboard, showing three bands at different deflection angles and spectral widths; stacked prisms visible at right

Safety

Deflection and Dispersion

Compares deflection and chromatic dispersion across three prism materials (acrylic, glass, ethyl cinnamate). Students learn that deflection angle depends on refractive index while spectral width depends on material dispersion -- …
