- 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 one cycle in a repeating event, so the period is the reciprocal of the frequency.

frequency frequency. 1. the number of occurrences of a periodic or recurrent process in a unit of time, such as the number of electrical cycles per second measured in hertz. In cardiac pacing terminology, frequency is expressed by the formula: frequency = ½ × pulse width.

- In this case, there is 1 cycle per 60 seconds. So the frequency is f = 1 cycle / (60 s) = (1 / 60) Hz. Answer: A. Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second.

Frequency Distribution What Is a Frequency Distribution? A frequency can be defined as how often something happens. For example, the number of dogs that people own in a neighborhood is a frequency. A distribution refers to the pattern of these frequencies. A frequency distribution looks at how frequently certain things happen within a sample of values.

What is the difference of frequency distribution and relative frequency distribution? Frequency distribution refers to a set of frequencies with a  particular set of values into which a statistical population is  grouped. Relative frequency refers to data pre…sented in a table  that demonstrates the relative frequency of multiple  non-overlapping classes.

Communications System Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.Usually frequency is measured in the hertz unit, named in honor of the 19th-century German physicist Heinrich Rudolf Hertz. The hertz measurement, abbreviated Hz, is the number of waves that pass by per second.For example, an A note on a violin string vibrates at about 440 Hz (440 vibrations per second).o if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour. Usually frequency is measured in the hertz unit, named in honor of the 19th-century German physicist Heinrich Rudolf Hertz.

- Frequency is the number of pressure waves that pass by a reference point per unit time and is measured in Hertz (Hz) or cycles per second. To the human ear, an increase in frequency is perceived as a higher pitched sound, while a decrease in frequency is perceived as a lower pitched sound.

- Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second. In this case, there is 1 cycle per 2 seconds. So the frequency is 1 cycles/2 s = 0.5 Hz. 6.

Frequency If the period, or time interval, required to complete one cycle or vibration is 1/2 second, the frequency is 2 per second; if the period is 1/100 of an hour, the frequency is 100 per hour. In general, the frequency is the reciprocal of the period, or time interval; i.e., frequency = 1/period = 1/(time interval). The frequency with which the Moon revolves around Earth is slightly more than 12 cycles per year. The frequency of the A string of a violin is 440 vibrations or cycles per second.

- The frequency of a wave has the same meaning as the frequency of anything else. It means how often something happens in a given time. For example, three buses an hour might be the frequency of buses on one route. With waves, frequency is how many peaks go past in a given time, usually one second.

Definitions &Translations Frequency. 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 one cycle in a repeating event, so the period is the reciprocal of the frequency.

Frequency and Period of a Wave Frequency and period are distinctly different, yet related, quantities. Frequency refers to how often something happens. Period refers to the time it takes something to happen. Frequency is a rate quantity. Period is a time quantity. Frequency is the cycles/second. Period is the seconds/cycle. As an example of the distinction and the relatedness of frequency and period, consider a woodpecker that drums upon a tree at a periodic rate. If the woodpecker drums upon a tree 2 times in one second, then the frequency is 2 Hz.

- The frequency of a wave is the number of waves produced by a source each second. It is also the number of waves that pass a certain point each second. The unit of frequency is the hertz (Hz). It is common for kilohertz (kHz), megahertz (MHz) and gigahertz (GHz) to be used when waves have very high frequencies.

Frequency Three cyclically flashing dots from lowest frequency (top) to highest frequency (bottom). For each dot, f is the frequency in hertz (Hz) – meaning the number of times per second (i.e. cycles per second) that it flashes – while T is the flashes' period in seconds (s), meaning the number of seconds per cycle.or counts per unit of time, the SI unit for frequency is hertz (Hz), named after the German physicist Heinrich Hertz; 1 Hz means that an event repeats once per second. A previous name for this unit was cycles per second (cps).

frequency (plural frequencies). ( 1 uncountable) The rate of occurrence of anything; the relationship between incidence and time period. ( 2 uncountable) The property of occurring often rather than infrequently. ( 3 countable) The quotient of the number of times a periodic phenomenon occurs over the time in which it occurs:

Frequency For cyclical processes, such as rotation, oscillations, or waves, frequency is defined as a number of cycles per unit time. In physics and engineering disciplines, such as optics, acoustics, and radio, frequency is usually denoted by a Latin letter f or by the Greek letter or ν (nu) (see e.g.Planck's formula).requency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio (sound) signals, radio waves, and light.

Frequency Frequency. This is less well understood, but is easy if you look at the word. Frequency means how frequent. In other words, how often something happens. In physics, we normally expect frequency to be how many times something happens per second.For a wave, frequency means: how many waves per second.n other words, how often something happens.

Frequency distribution In statistics, a frequency distribution is a table that displays the frequency of various outcomes in a sample.Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample.n statistics, a frequency distribution is a table that displays the frequency of various outcomes in a sample.
