A sine wave is a smooth, repeating wave that represents many natural and technical signals such as sound waves, radio waves, and AC electricity.
The frequency of a sine wave tells us how many complete cycles occur in one second. It is measured in Hertz (Hz).
If a sine wave completes:
Higher frequency means faster oscillation. Lower frequency means slower oscillation.
Manually calculating frequency can be confusing, especially when working with radians, angular frequency, or time periods. Small mistakes can lead to wrong answers.
Our online sine wave frequency calculator helps you:
It is perfect for physics problems, electronics projects, and signal analysis.
There are three main ways to calculate sine wave frequency. Our calculator supports all of them.
If your sine wave is written as:
y(t) = sin(bt)
Then the frequency formula is:
f = b / (2π)
Where:
If you know the time of one complete cycle, use this formula:
f = 1 / T
Where:
If angular frequency is given:
ω = 2πf
Then frequency is:
f = ω / (2π)
Where:
These formulas are used worldwide in physics and engineering. Our calculator applies them automatically.

Let us understand with a simple example.
Given:
b = 200π rad/s
Formula:
f = b / (2π)
Calculation:
f = (200π) / (2π)
f = 100 Hz
So, the frequency is 100 Hz.
Given:
T = 0.02 seconds
Formula:
f = 1 / T
Calculation:
f = 1 / 0.02
f = 50 Hz
So, the frequency is 50 Hz.
Given:
ω = 314 rad/s
Formula:
f = ω / (2π)
Calculation:
f = 314 / (6.283)
f ≈ 50 Hz
So, the frequency is about 50 Hz.
These examples show how simple frequency calculation becomes with our tool.

Try it today and calculate sine wave frequency in seconds.
The frequency of a sine wave is the number of complete cycles it makes in one second. It is measured in Hertz (Hz).
You can calculate frequency using these formulas:
From angular coefficient: f = b / (2π)
From period: f = 1 / T
From angular frequency: f = ω / (2π)
Our calculator does this automatically.
Frequency is measured in Hertz (Hz). One Hertz means one cycle per second.
