Rpm is calibrated with triangular glass (5) Crossword Clue
Answer: PRISM (5 letters)
The answer to the crossword clue "Rpm is calibrated with triangular glass" with 5 letters is "PRISM".Prism is a triangular glass object that can refract light, often used in optical experiments. In the context of the clue, it could metaphorically refer to the way light is measured or calibrated, similar to how precision tools are calibrated in various scientific fields.
Why “Prism” Fits
The clue asks for a 5-letter word meaning “triangular glass,” with wordplay involving “rpm is calibrated.” The answer, PRISM, fits neatly:
- Triangular glass: A "prism" is a geometric glass object, typically triangular, that disperses light into its component colors and is widely recognized for this optical effect in science and popular culture.
- Clue structure: The clue cleverly signals an anagram (“calibrated” as the indicator) of “rpm is,” forming "prism," which directly refers to the triangular glass commonly seen splitting light into a spectrum.
This term is a textbook example of physical objects in both optics and cryptic crossword wordplay.
“Prism” is fundamental to physics, art, and everyday life:
- Origin and use: The word comes from the Greek "prisma," meaning "something sawed," and is used in science classes, photography, and music album covers.
- Optical function: A prism’s classic shape allows it to refract and scatter white light into a rainbow of colors. Pink Floyd’s "Dark Side of the Moon" features a prism, a motif familiar to fans and crossword solvers alike.
- Practical context: Prisms are used in binoculars, cameras, and design; "prism glass" refers to cut glass that bends and splits incoming light.
“Prism” naturally bridges the clue’s requirements for shape, material, and effects with its neat anagrammatic formation.
In quick and cryptic crosswords, clues like “triangular glass (5)” or cryptic wordplay from “rpm is”:
- Direct solvers toward succinct technical nouns—“prism,” “lens,” “panel.”
- The answer length (5) and the context—light and glass—make "prism" an immediate fit.
- Cryptic clues often disguise simple answers with elegant anagrams (“rpm is” = "prism").
Spotting the optical reference and wordplay quickly leads to “prism.”
