Given, f=100 Hz
To find: a) Time period (T)
b) No. Of vibrations (N)
Solution:
Part (a)
Time Period,
T= 1/100 = 0.005 sec
Part (b)
No. of Vibrations,
N= Total time/ Time Period
= 60/0.005
= 12000

time period=1/frequency=1/200=0.005
T=time taken by 1st crest/number of times
0.005=60/n
1/n=0.005/60
n=60/0.005
=12000
T=time taken by 1st crest/number of times
0.005=60/n
1/n=0.005/60
n=60/0.005
=12000
