Period and Frequency Calculator
Period and Frequency Calculator
Enter either period (T, seconds) or frequency (f, hertz) - the calculator will automatically compute the other value.
Relationship between period and frequency:
Period and frequency are inversely related:
- Frequency formula: f = 1/T
- Period formula: T = 1/f
Definitions:
- Period (T): Time for one complete cycle, measured in seconds (s)
- Frequency (f): Number of cycles per second, measured in hertz (Hz)
Examples:
- 60 Hz AC power: T = 1/60 = 0.0167 seconds
- Pendulum with T = 2s: f = 1/2 = 0.5 Hz
- Radio wave 100 MHz: T = 1/(100×10⁶) = 10 nanoseconds
Applications:
- Sound and audio engineering
- Radio and telecommunications
- Mechanical vibrations
- Electrical circuits (AC analysis)
- Wave physics
Frequently Asked Questions
How are period and frequency related?
Period (T) and frequency (f) are related by: T = 1/f, f = 1/T. This calculator helps quickly convert between values.
How to calculate frequency if period is known?
Frequency is calculated using f = 1/T, where T is the period in seconds.
What is this period and frequency calculator used for?
This calculator helps quickly and accurately compute period or frequency, important in physics, electronics, and engineering.
What units are used for period and frequency?
Period is measured in seconds (s), and frequency in hertz (Hz), which corresponds to cycles per second.
Can I enter both period and frequency simultaneously?
No, enter only one value. The calculator will compute the other automatically.
