Solution
The correct option is A glass prism
When the light is passed through any glass prism it splits into its spectrum of colours (of different wavelengths). This phenomenon of light splitting into its constituent colours is termed as dispersion of light. In T.W. Engelmann’s experiment, prism was used to split the light.
Gemstone and quartz which are mineral crystals do not serve the same practical purpose like the glass prism.
