A marine weather station reports waves along the shore that are 8 seconds apart, the frequency of the waves is 0.125Hz.
Answer: Option D
Explanation:
A weather station informs that the waves along the shore are 8 seconds apart. Frequency is related to the time period traveled by the object hence it is inversely proportional to the frequency. The time period here is referred as 8 seconds. Therefore frequency = 1 / 8 = 0.125 Hz.
