Prism bụ polyhedron nke ejiri ihe na-ahụ anya (dị ka iko, kristal, wdg). A na-ejikarị ya eme ihe na ngwa anya. Enwere ike kewaa prisms n'ụdị dị iche iche dabere na njirimara na ojiji ha siri dị. Dịka ọmụmaatụ, n'ime ngwa spectroscopic, "prism dispersion" nke na-emebi ìhè mejupụtara n'ime spectra ka a na-ejikarị eme ihe dị ka prism equilateral; N'ime ngwa ndị dị ka periscopes na teliskop binocular, ịgbanwe ntụziaka nke ìhè iji dozie ọnọdụ onyonyo ya ka a na-akpọ "prism zuru oke". "Prisms na-egosipụta" na-ejikarị prisms akụkụ aka nri.
Akụkụ nke prism: ụgbọ elu nke ìhè na-abanye na ọpụpụ na-akpọ akụkụ.
Isi akụkụ nke prism: ụgbọ elu perpendicular n'akụkụ a na-akpọ isi ngalaba. Dị ka udi nke isi ngalaba si dị, enwere ike kewaa ya ka ọ bụrụ prisms triangular, prisms akụkụ aka nri, na prisms pentagonal. Akụkụ bụ isi nke prism bụ triangle. Prism nwere akụkụ abụọ na-emegharị emegharị, akụkụ dị n'etiti ha ka a na-akpọ apex, ụgbọ elu chere ihu n'elu bụ ala.
Dị ka iwu nke ntugharị si dị, ray na-agafe na prism ma na-atụgharị ugboro abụọ gaa n'elu ala. Akụkụ q dị n'etiti ray na-apụ apụ na ray merenụ ka a na-akpọ akụkụ mgbapụ. A na-ekpebi ogo ya site na ntugharị refractive n nke priism media na akụkụ ihe merenụ i. Mgbe a na-edozi m, ebili mmiri dị iche iche nke ìhè nwere akụkụ ntụgharị dị iche iche.
