Frequency can be applied to any kind of motion that is repetitive. It answers the question; "how frequent does the cycle repeat itself?" Then it is expressed by counting how often the motion repeats in a certain amount of time and dividing that count by the time. For example if 12 complete waves (or cycles) pass a point in 6 seconds then the frequency is 12/6 = 2 cycles/sec. The unit of 1 cycle/sec is called a Hertz so the frequency would also be expressed as 2 Hertz or 2 Hz.
Hertz.
Frequency is a metric for expressing the rate of oscillation in a wave. For planar and longitudinal waves, this often expressed in oscillations-per-second or Hz. Angular frequency used for expressing rates of rotation, similar to revolutions-per-second, and is usually expressed in radians-per-second. It can be thought of as a wave with a constant amplitude where the amplitude rotates in a circle in space. The two differ by factor of 2*Pi. Omega (angular frequency) = 2*Pi*f(frequency in Hz)
The number of cycles per second, or frequency, is expressed in hertz, abbreviated Hz.
A frequency distribution with the total frequency equated to one hundred and the individual class frequencies expressed in proportion to that figure. :) Im so smart ;) No one better improve this answer.You welcome Person who asked this question.
It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.
Rule or principle frequency expressed in statistical symbols?
Hertz.
in form of percent
formula
dynamic frequency, which is cycles per second, or Hertz
It is the observed frequency divided by the total number of observations, expressed as a percentage.
a measure of the degree of frequency modulation expressed numerically for a pure tone modulation as the ratio of the frequency deviation to the frequency of the modulating signal.
Frequency is expressed in cycles per second, which is the same as Hertz. Frequency can also be expressed in kilohertz, megahertz, or gigahertz. So an AM radio station might be 700 KHz, an FM station might be 88.1 MHz, and a microwave might be 2.4 GHz.

Blade Pass Frequency is the number of blades/vanes passing a particular point in the casing of a pump/fan in unit time. It can be expressed in s-1 units or hertz.
CAPACITOR'S REACTANCE CHANGES WITH FREQUENCY WHEREAS A BATTERY'S RESISTANCE IS FIXED. ALSO BATTERY STORES ENERGY AND IS EXPRESSED IN UNITS AS AMPERE-HOURS, WHERE AS CAPACITOR STORES CHARGE AND AND IS EXPRESSED IN UNITS AS MICRO / NANO FARADS
