Answer:
Option B. 0.3 Hz
Explanation:
From the question given above, the following data were obtained:
Period (T) = 3 s
Frequency (f) =?
Frequency is related to the period according to the following equation:
Frequency (f) = 1 / period (T)
f = 1/T
With the above formula, we can obtain the frequency wave as illustrated below:
Period (T) = 3 s
Frequency (f) =?
f = 1/T
f = 1/3
f = 0.3 Hz
Therefore, the frequency of the wave is 0.3 Hz
