Respuesta :
The period frequency of the wave striking the fisherman's boat side is 0.25 Hertz.
What is Frequency?
Frequency is simply the number of occurrences of an event repeated per unit of time.
Period is simply the time taken for a complete cycle of vibration to pass a given point. Frequency is expressed as;
f = 1/T
Where f is frequency and T is period of time.
Given that;
- Time period T = 5seconds
- Frequency f = ?
f = 1 / T
f = 1 / 4s
f = 0.25s⁻¹
f = 0.25Hz
Therefore, the period frequency of the wave striking the fisherman's boat side is 0.25 Hertz.
