frequency
Meaning: How often something happens; the rate at which something occurs
Frequency describes how often something happens within a period of time. In physics, it refers to the number of waves passing a point per second, measured in hertz (Hz). Radio stations broadcast on specific frequencies. High frequency means something happens often; low frequency means rarely.
