What is the frequency of a wave with a period of 7s? 2.4E-3Hz ) 0.14 Hz 8.57 Hz ) 7 Hz

To find the frequency of a wave with a period of 7 seconds, we can use the formula:Frequency (f) = 1 / Period (T)Given that the period (T) is 7 seconds, we can substitute this value into the formula:Frequency (f) = 1 / 7 secondsCalculating this, we get:Frequency (f) = 0.14 HzTherefore, the correct answer is 0.14 Hz.
