What is the period, in seconds, that corresponds to each of these frequencies?

Question

(A) 10 Hz
(B) 0.2 Hz
(C) 60 Hz

Answer 1

period (s) = 1/frequency (hz)

so:

(a) = 1/10 s = 0.1 s
(b) = 1/0.2 s = 5 s
(c) = 1/60 s = 0.01666... s

Answer 2

It turns out that any periodic signal (one that repeats itself at regular intervals) is equal to a sum of sines and cosines. The frequencies of the component sines and cosines are just the frequency of the original periodic signal (the fundamental frequency), plus the “overtones”, i.e. the integer multiples of the fundamental frequency.



If the period (repeat time) of the signal is T seconds, then the frequency (in cycles/sec, or Hertz) is f=1/T. The sines and cosines will have frequencies of f, 2f, 3f, etc. For example, if the signal repeats every 1.25 sec, f=0.8 Hz, and the component sines and cosines have frequencies of 0.8, 1.6, 2.4 Hz, etc. The Fourier series for a signal x(t), which has a period of T,
Mean frequency and median frequency are sometimes used to summarize, in a statistical sense, the frequency content of a signal. These quantities are defined exactly as median and mean are usually defined in statistics

Answer 3

so a concepts as I all persons comprehend radio frequency / RF travels on the cost of light or on the factor of it . Radio frequency is tormented by way of the ambience and a few thing this is occurring in or on the factor of it .RF radio frequency is tormented by way of in simple terms approximately each and every factor .A radio transmit ion will leap throughout the time of the ambience like an mind-blowing ball in a hallway . it does no longer consistently take the shortest direction yet so a concepts because of the fact this is unquestionably-time-commemorated it travels at approximately the cost of light . electrical energy additionally travels at with connection with the cost of light this is extremely speedy . think of of roughly it you have a telephone call with somebody this is on the different factor of the international and there is not any placed off which you would be conscious . RF works corresponding to a magnet which you will activate and off very with out placed off, the transmitter factors off a electromagnetic pulse in to the ambience. A receiver listens for the guts beat and converts it to an audible sign and strikes a speaker cone on the modulated frequency . ok this is possibly too lots counsel yet think of of roughly it for a on a similar time as and it may make adventure .

Answer 4

period [cycle] = 1/frequency

Therefore,
a. 1/10 = 0.1 seconds
b. 1/0.2 = 5.0 seconds
c. 1/60 = 0.0167 seconds

Hope this helps!
