A hollow glass prism gives no spectrum because it has no medium inside. It is hollow from the inside, so white light can not split in a vacuum because in a vacuum, all colors of light travel with the same speed; hence they do not split, and no spectrum is observed. A beam of white light passing through a hollow prism gives no spectrum. The dust created from cutting or milling Glass is not carcinogenic when inhaled; excessive inhalation over long periods can lead to breathing problems such as asthma. A hollow prism is made using a glass plate with the center part of the prism vacant. This cavity can be filled with gas or other fluids. Thus, a hollow prism is also commonly called a fluid prism. Hollow Glass Microspheres. Hollow glass microspheres, also called bubbles, microbubbles, or micro balloons, provide the benefits of low density, high heat, and chemical resistance. Acrylic (PMMA) is a transparent and rigid thermoplastic material widely used as a shatterproof replacement for Glass. Benefits: It is optically clear, UV stable, and exhibits glass-like quality at half the weight with up to 10 times the impact resistance. All the colors travel with the same speed in the air inside a hollow prism. Under such circumstances, no dispersion can occur. We have studied that glass powder is insoluble in water. This means it will not form a clear mixture if we try to dissolve it in water. One of the advantages of glass powder and glass abrasives, in general, is high purity – thanks to that, it is used in the chemical industry to produce cleaning agents and wash powders. Glass sand works perfectly as an insulator and filler – it is used in chemical production.
