1. Frequency

   Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity, and is distinct from angular frequency. Frequency is measured in hertz (Hz) which is equal to one event per second. The period is the interval of time between events, so the period is the reciprocal of the frequency.For example, if a heart beats at a frequency of 120 times a minute (2 hertz), the period, T—the interval at which the beats repeat—is half a second (60 seconds divided by 120 beats). 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.

1. 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. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period is half a second.

Examples of frequency in a Sentence

1. Oklahoma University:

   We are very excited about this discovery. This is the first time anyone has discovered planets outside our galaxy, these small planets are the best candidate for the signature we observed in this study using the microlensing technique. We analyzed the high frequency of the signature by modeling the data to determine the mass.

2. Samuel Dagogo-Jack:

   For example, we ca n’t check blood sugar noninvasively, we have to stick the patient’s finger or draw blood from a vein. So when in hospice, we relax the goals of treatment and we also make the decision of what is rational as far as the frequency in testing blood sugar levels. We have to practice the principle of doing no harm and maximizing the comfort of the patient.

3. Tobin Cooley:

   Higher frequencies like this tone are very directional sounds, versus low-frequency sounds which can seem to come from anywhere or everywhere at once, what surprises me is that neighbors have not been able to locate where this is coming from.

4. Neil Gershenfeld:

   For a smart material to be able to send out a more complex signal it needs to be nonlinear. If you hit a tuning fork twice as hard it will ring twice as loud but still at the same frequency. That's a linear response. If you hit a person twice as hard they're unlikely just to shout twice as loud. That property lets you learn more about the person than the tuning fork.

5. Adam Smith:

   What's concerning about National Oceanic and Atmospheric Administration is it's yet another year in a series of years where we have both a high frequency, high cost and a large diversity of these extreme events that affect people's lives and livelihoods, over the last five years, the United States has experienced almost $ 750 billion of damages from these billion-dollar disasters, which is really off the charts.
