Question

If 225 oscillations are produced in 5 seconds, what is the frequency and time period?​

Answer 1

freq = no. of oscillation/sec

= 225/5

= 45 Hz

Time period = 1/frequency

= 1/45

= 0.022 s

Answer 2

Answer:

Frequency is 45Hz and time period is 0.23 seconds

Explanation:

We know frequency is number of oscillations in one second

So, frequency=225/5

                      =45Hz

As, Time period is inversely proportinal to frequency.

So, Time period = 1/ frequency

                           =1/45

                           =0.0226 s

                           =0.023 s
