Answer:
Frequency = 0.0167 Hz
Explanation:
Given the following data;
Number of waves = 40
Period, T = 80 seconds
To find the frequency of the wave;
Frequency = 1/period
Substituting into the equation, we have;
Frequency = 1/60
Frequency = 0.0167 Hz
Therefore, the frequency of the waves is 0.0167 Hertz.
