Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period â the interval between beats â is half a second (60 seconds (i.e., a minute) divided by 120 beats).or each dot, f is the frequency in hertz (Hz) â meaning the number of times per second (i.e. cycles per second) that it flashes â while T is the flashes' period in seconds (s), meaning the number of seconds per cycle. Each T and f are reciprocal.
The last name Kuznetsov is most common among Russian family names in the region from Upper Oka to Middle Volga. In English, there is also a similar last name â Smith. 4. Popov. The last name Popovpoints directly to the occupation of the father â pope (priest).
