A period can't be 4 Hz; those are the wrong units.
If the period is 1/(4Hz), then the frequency is 4Hz.
If the period is 4 seconds, then the frequency is 0.25 Hz. They are inversely related.

Frequency = number of cycles per second (Hertz, Hz)

so

Frequency = 4 cycles in 3 seconds = 4/3 Hz or 1.333 Hz

Clock waveform whose frequency is 2MHz?

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.


What is the frequency of a clock waveform whose period is 20 microseconds?

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.


What is the frequency of a wave whose period is 5.5 seconds?

Frequency = 1/period = 1/5.5 = 0.182 Hz(rounded)


How do you find the period of middle c whose frequency is 256Hz?

Period = reciprocal of ('1' divided by) the frequency = 1/256 = 0.00390625 second


What is the period of a wave whose frequency is 2MHz?

The period is the reciprocal of the frequency. 1 / 2 million Hz = 500 ns or 0.5 us (microseconds).


What is the frequency of a wave whose period is 4 x 10-7 seconds?

The frequency is the reciprocal of the period; in this case, divide 1 / 4x10-7.


What is the time period of a turning fork whose frequency is 200Hz?

Time period T = 1 / frequency f. Frequency f = 1 / time period T. T = 1 / f = 1 / 200 = 0.005 seconds = 5 milliseconds.


What is an atomic clock?

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.


A boat at anchor is rocked by waves whose crest are 40m apart and whose speed is 10ms these waves reach the boat once every?

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.)

What is the period T of a wave whose Frequency is 5.0 Hz?

T = 1/f T = 1/(50 Hz) = .02 sec


What is the period of a sound wave whose wave length is 20.0 m?

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.
