Question

An object vibrates 60 times in 4 seconds. Find its time period and frequency?​

Answer 1

Solution :-

Given :
An object vibrates 60 times in 4 seconds.


Find the frequency :-

We know that,
Frequency = (Number of Oscillations)/Time
= 60/4 = 15 Hertz


Find the time period :-

We know that,
Time period = 1/(Frequency of Oscillation)
= 1/15 = 0.15 seconds


Hence,
Time period = 0.15 seconds
Frequency = 15 Hertz

Answer 2

Question :

An object vibrates 60 times in 4 seconds. Find its time period and frequency?

Solution :

As we know ,

Frequency = Number of Oscillations / Time Taken

= 60/4 = 15 Hz

Then ,

Time Period = 1/ Frequency = 1/15 Seconds = 0.15 seconds
