प्रश्न
Obtain relationship between the time period and frequency.
उत्तर
- Frequency is the number of times a cycle is completed in a second.
- The frequency & time period is inversely proportional.
The number of vibrations per second is called frequency
The s.i unit of frequency is Hertz. - The time taken to complete one vibration is called time period.
Relationship between the Time Period (T) and Frequency (ƒ): By definition time period is the time taken to complete 1 vibration
Or
In time T, the number of vibration= 1
∴ In 1 second, the frequency or number of vibrations = 1 / T
`ƒ = 1 / t Or t = 1 / ƒ`
