What is the period that corresponds to a
frequency of 39.5 Hz?
Answer in units of s.

The answer for the following problem is mentioned below.

Explanation:

Frequency:

The number of waves that pass a fixed place in a given amount of time. (or)

The number of waves that pas by per second.

The SI unit of the frequency is Hertz(Hz).

Time period:

The time taken for one complete cycle of vibration to pass a given point.

The SI unit of time period is seconds. (s)

Given:

Frequency (f) = 39.5 Hz

To calculate:

Time period (T)

We know;

According to the problem;

From the problem;

f =

Where;

f represents the frequency

T represents the time period

 f =

 f = 0.02 seconds

Therefore the time period is 0.02 seconds.
