About This Product
Filled with water or another clear liquid and set on a spectrometer, the prism gives the minimum deviation from which the liquid’s refractive index is calculated. Changing the liquid lets a class compare media in one experiment.
Frequently Asked Questions
Can different liquids be used in the Hollow Equilateral Prism?
Yes. It is designed to hold transparent liquids so their refraction and dispersion can be compared.
