Question

the frequency of a given sound is 3.5KHZ. how many vibration it completes in one second

Answer 1

Since, f = 1/t

Where f is 3500 Hz

Then no.of vibration or oscillation will be 3500 in 1 sec.

CONCLUSION: IF FREQUENCY IS GIVEN THEN EITHER CONVERT IT IN HERTZ OR LEAVE IT IF IT IS IN HERTZ, AND MULTIPLY WITH TIME IN SECOND TO FIND THE NO. OF VIBRATION
