A sound wave travels 30 oscillationsin 5 seconds. calculate its frequency and its time period .

Open in App

Solution

No of oscillations = 30
Time taken = 5 sec
Frequency = No of oscillations in 1 second = 30 / 5 = 6 Hz or 6 oscillations per second
Time period = Time taken for 1 oscillation = 1/ frequency = 1/6 = 0.167 sec
