Question

If 250 oscillations are produced in 5 seconds, what is the frequency and time period ?

Answer 1

Answer:

Frequency = 50Hz , Time Period = 0.02 sec.

Explanation:

Frequency is, actually, the number of oscillations produced by the oscillator in 1 second.

Thus by definition, Frequency = (No. of Oscillations)/(Time taken to complete them) = 250/5 = 50Hz.

And, time period (T) is, basically, the reciprocal of Frequency of oscillations (f).

Thus, Time Period = 1/Frequency = 1/50 = 0.02 sec.

Answer 2

Frequency = (NO.OF.oscillation)/time taken to complete those

⇒ Frequency = 250/5 = 50 Hz

Time Period = 1/Frequency

⇒ Time Period = 1/50 = 0.02 sec
