The frequency of the vibrating body with the given value of time period is 2.5Hz.
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;
f = 1/T
f = 1/0.4s
f = 2.5s⁻¹
f = 2.5Hz
Therefore, the frequency of the vibrating body with the given value of time period is 2.5Hz.
