Everything about Frequency
Number of occurrences or cycles per unit time
Frequency is the number of occurrences of a repeating event per unit of time. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. Wikipedia →

📖 Definitions
Noun The rate of occurrence of anything; the relationship between incidence and time period.
Noun The property of occurring often rather than infrequently.
Noun The quotient of the number of times n a periodic phenomenon occurs over the time t in which it occurs: f=n/t.
Noun A tone, character, mood, or vibe
