Answer: 0.2Hz
Explanation:
Given that
period of wave (T) = 5.0 seconds
frequency of wave (F) = ?
The frequency (F) of a wave is the number of cycles which the wave complete in one second. Thus, it is inversely proportional to the period (T) of the wave, and its unit is Hertz
Hence, apply the formula F = 1/T
F = 1/5.0 seconds
F = 0.2Hz
Thus, the frequency of the wave is 0.2Hz
