a photographic record of light interference patterns produced with an interferometer, used for recording shock waves and fluid flow patterns
Word origin
[1920–25; interfere + -o- + -gram1]This word is first recorded in the period 1920–25. Other words that entered Englishat around the same time include: Unknown Soldier, fundamentalism, self-service, ski jump, zipper-gram is a combining form occurring in loanwords from Greek, where it meant “somethingwritten,” “drawing” (epigram; diagram). On this model, -gram is used in the formation of compound words (oscillogram)
