Frequency = number of cycles per second (Hertz, Hz)
so
Frequency = 4 cycles in 3 seconds = 4/3 Hz or 1.333 Hz
f=1/T
f=1/0.46
f=2.17Hz
It is 1/4000000 seconds.
Frequency = 1/period = 1/5.5 = 0.182 Hz(rounded)
The period is the reciprocal of the frequency. 1 / 2 million Hz = 500 ns or 0.5 us (microseconds).
Time period T = 1 / frequency f. Frequency f = 1 / time period T. T = 1 / f = 1 / 200 = 0.005 seconds = 5 milliseconds.
You are supposed to use the basic formula for waves: speed = wavelength x frequency. In this case, you have to solve for frequency. (The period is the reciprocal of the frequency.)
You solve this as follows: 1) Decide on a number for the speed of sound. Note that the speed of sound in air is quite different to the speed of sound in water, for example. Convert this speed to meters/second, if it isn't already in meters/second. 2) Divide the speed by the wavelength, to get the frequency. 3) The period is simply the reciprocal of the frequency.
If the question is what is the waveform for 2 Mhz, then 500nS is the answer (equasion used is f=1/t) If the question is what is the waveform for 2mHz, then 500 S is the answer.
The period T is the time for one complete cycle of an oscillation of a wave. The frequency f is the number of periods per unit time (per second) and is measured in Hz, or cycles per second. These are related by: f = 1/T Therefore, for a period of T = 20µs = 20*(10^-9)s, f = 1/(20*(10^-9)) f = 20*(10^9) f = 20,000,000,000 Hz = 20 GHz.
Frequency = 1/period = 1/5.5 = 0.182 Hz(rounded)
Period = reciprocal of ('1' divided by) the frequency = 1/256 = 0.00390625 second
The period is the reciprocal of the frequency. 1 / 2 million Hz = 500 ns or 0.5 us (microseconds).
The frequency is the reciprocal of the period; in this case, divide 1 / 4x10-7.
Time period T = 1 / frequency f. Frequency f = 1 / time period T. T = 1 / f = 1 / 200 = 0.005 seconds = 5 milliseconds.
An atomic clock is a reference clock whose operation is based on an atomic process, such as the frequency of electromagnetic radiation associated with a specific energy-level transition in an element such as caesium.
You are supposed to use the basic formula for waves: speed = wavelength x frequency. In this case, you have to solve for frequency. (The period is the reciprocal of the frequency.)

T = 1/f T = 1/(50 Hz) = .02 sec
You solve this as follows: 1) Decide on a number for the speed of sound. Note that the speed of sound in air is quite different to the speed of sound in water, for example.
