Answer:
Step-by-step explanation:
A pain vibrates 262 times in 5seconds
The period of a vibration or wave is the time for one complete vibration. When an object makes one vibration per second its frequency is said to be 1 hertz.
Then, the frequency of oscillation is
262 / 5Hz
F = 52.4 Hz
Then,
f = 1 / T
Where
f = frequency
T = period
So, it completes 262 oscillation in 5seconds
Where one oscillation is one period
Then,
Each oscillation will be
T = 5 / 262
T = 0.0191 seconds
T = 19.1 ms
The period of oscillation is 19.1 ms
Or by using
T = 1 / f
T = 1 / 52.4
T = 0.0191s
T = 19.1 ms
