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.
What else can I help you with?
What unit is frequency expressed?
Hertz.
What is a difference between frequency and angular frequency?
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)
What is measured by the number of ticks per second?
The number of cycles per second, or frequency, is expressed in hertz, abbreviated Hz.
What is the definition of percent distribution?
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.
How the 40 meters wave length is equal to 7 mhz frequency?
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.

Hertz.
What is the frequency of the keyword in the given context when expressed as w/2 pi?
To find the frequency of the keyword in the given context when expressed as w/2, you need to divide the angular frequency (w) by 2.
Is the cummulative frequency distribution a relative frequency distribution expressed in absolute numbers?
in form of percent
Which property is expressed in units of hertz?
dynamic frequency, which is cycles per second, or Hertz
What is a Rule or principal frequency expressed in statistical symbols?

What does the word relative frequency as a decimal mean in math?
It is the observed frequency divided by the total number of observations, expressed as a percentage.
Define modulation and modulation index?
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.
What does the frequency of sound measure?
The frequency of sound is measured in "Hertz (Hz)".
How does the amplitude and frequency affect wavelength?
The amplitude of a wave does not affect its wavelength as wavelength is determined by the speed of the wave and its frequency. Frequency and wavelength are inversely proportional; as frequency increases, wavelength decreases, and vice versa. This relationship is expressed mathematically as wavelength = speed of the wave / frequency.
AM radio dials are calibrated in frequency. A certain AM Brockville radio station broadcasts at a frequency of 830 kHz. What is the wavelength of these radio waves expressed in meters?
