prism
含义: A solid geometric shape whose two ends are identical parallel polygons connected by rectangular faces, or a transparent triangular block that disperses white light into a spectrum of colours.
In geometry, a prism is defined by having a uniform cross-section along its length. In optics, a triangular glass prism refracts light at different angles depending on wavelength, separating it into the visible spectrum. Figuratively, 'through the prism of' means viewing something from a particular perspective or framework.
