PASSAGE-II: The number of oscillations or vibrations made by a vibrating body in one second is known as the frequency of the wave. The S.I. unit of frequency is hertz (Hz) which is named after the name of scientist Heinrich Hertz. Time taken to complete one vibration by the vibrating body is known as time period. Time period and frequency are related as "Time periode" = 1/("frequency") A vibrating body vibrates 200 times in 5 second, calculate its frequency?

Time period and frequency are related as "Time periode" = 1/("frequency") A boy heard a sound of frequency 100 Hz at a distance of 500 m from the source of sound. What is the time period of oscillating particles of the medium?
