Question

An oscillater oscillates 90 times in one minute find the time period and frequency​

Answer 1

Answer:

Given

90 oscillations => 60 sec

Time period is defined as time taken for 1 oscillation

1 oscillation => 60 / 90 sec

                   => 2/3 sec

so time period is 2/3 sec

Frequency is defined as number of oscillation made in one second

60 sec => 90 oscillations

   1 sec => 90/60 oscillations

            => 3/2 oscillations

so frequency is 3/2 Hz
