Frequency Calculator: Find Wavelength & Period
This Frequency Calculator helps you figure out how frequency, wavelength, and time period are related. You can use it to convert between these measurements, which is helpful for understanding things like Wi-Fi, Bluetooth, 4G, and 5G signals. Just enter the values you know, and the calculator will find the rest!
Understanding Frequency, Wavelength, and Time Period
What is Frequency?
Frequency tells you how many times something happens in one second. We measure it in Hertz (Hz). For example, if a wave repeats itself 5 times a second, the frequency is 5 Hz. Think about it like this: if you swing back and forth on a swing set really fast, you have a high frequency.
Understanding Wavelength
Wavelength is the distance between two peaks (or two valleys) of a wave. We measure it in meters (m). Imagine a wave in the ocean. The distance between the top of one wave and the top of the next is the wavelength.
What is the Time Period?
The time period is how long it takes for one complete cycle of a wave to happen. We measure it in seconds (s). It's the opposite of frequency. If something has a high frequency, it has a short time period, and vice versa.
How to Use the Frequency Calculator
This calculator is super easy to use! Just follow these steps:
Choose the **Calculation Mode** based on what you want to calculate (e.g., Frequency to Wavelength).
Select the **Application Type** for relevant presets and default medium velocity.
Enter the known value (Frequency, Wavelength, or Time Period) in the corresponding input field. Make sure to select the correct unit.
Optionally, adjust the **Medium Velocity** if the wave is traveling through something other than a vacuum or air.
The calculator will automatically display the calculated Frequency, Wavelength, Time Period, and Angular Frequency in the **Results** section.
Scenarios Where You Might Use This Calculator
**Setting up Wi-Fi:** Find the wavelength associated with common Wi-Fi frequencies (2.4 GHz, 5 GHz).
**Working with Bluetooth devices:** Calculate the wavelength of the Bluetooth signal (around 2.4 GHz).
**Understanding 5G networks:** Determine the wavelengths for different 5G frequency bands (low-band, mid-band, mmWave).
**Electronics projects:** Calculate the period or wavelength for various electronic signals.
**General physics:** Convert between wave properties in different contexts.

How are Frequency and Wavelength Related?
Frequency ($f$) and wavelength ($\lambda$) have an inverse relationship. This means that when the frequency goes up, the wavelength goes down, and when the frequency goes down, the wavelength goes up. They are connected by the speed of the wave ($v$) in the medium. The formula is:
$v = f \times \lambda$
Where $v$ is the velocity of the wave (e.g., speed of light for electromagnetic waves), $f$ is the frequency, and $\lambda$ is the wavelength.
Interesting Facts About Frequency and Wavelength
Wi-Fi uses frequencies in the 2.4 GHz and 5 GHz bands, corresponding to wavelengths of approximately 12.5 cm and 6 cm in free space, respectively.
Bluetooth uses frequencies around 2.4 GHz, similar to Wi-Fi.
4G and 5G use different frequency bands depending on the country and carrier, ranging from below 1 GHz to tens of GHz, resulting in varying wavelengths.
Electromagnetic waves, like radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, are all forms of light and travel at the speed of light in a vacuum. They are distinguished by their frequency and wavelength.
The frequency of visible light determines its color. Red light has a lower frequency (longer wavelength), while violet light has a higher frequency (shorter wavelength).
