low-frequency
Not often happening
Low-frequency describes phenomena occurring rarely or at slow rates of repetition.
In physics and electronics, it characterizes waves or signals with few cycles per second, typically below 300 kilohertz for radio waves.
In linguistics and statistics, low-frequency words or events are those that appear infrequently in a given dataset or corpus.
Low-frequency vocabulary poses challenges for language learners.
The term contrasts with high-frequency across all these domains.
