Quick Answer: Prisms is an optics listing of optical prism for the practical study of refraction and dispersion of light. A beam bends at the first face, crosses the transparent body and bends again at the second face, so white light separates into a visible spectrum.

About This Product
Directing a narrow beam onto one face and turning the prism until the light emerges from the opposite face lets students measure angles of incidence, refraction and emergence. The coloured bands on a white screen give a direct view of dispersion and refractive index in physics practicals.
Frequently Asked Questions
Which light sources can be used?
A ray box, a laser beam, sunlight or another white light source directed onto one face of the prism.
