Question
Define the 'frequency' and 'time-period' of a wave. What is the relation between the two?
Solution
The number of complete waves or cycles produced in one second is called frequency of the wave.
The time required to produce one complete wave or vibration is called time period of the wave.
We know the relation between frequency and time period `f = 1/T`,
where f is the frequency and T the time period.
