what is the relationship between frequency and time period
Frequency (ν) is the number of complete oscillations or vibrations in 1 s. It is the inverse of time period (T).
So, the frequency is,
Unit of frequency is s-1or Hz (Hertz).
Time period of a wave is the time taken by a vibrating particle to make one complete vibration or it can be also defined as the time taken by a wave to move a distance equal to its wavelength. It is denoted by T. Its unit is second.
timePeriod and frequency are each others' reciprocals.
Time period = 1 / frequency.
Frequency = 1 / time period.
