In this article, we’ll explore how to calculate wavelength from frequency, provide an easy-to-follow formula, and highlight tools like a frequency to wavelength calculator for precise measurements. By the end, you’ll be ready to convert frequency to wavelength in meters with ease.
What is Frequency and Wavelength?
- Frequency ( f ): This measures how often a wave passes a fixed point in one second, measured in Hertz (Hz).
- Wavelength ( λ ): This is the distance between two successive wave peaks, typically measured in meters (m).
The relationship between these quantities is fundamental to understanding waves in physics.
Frequency to Wavelength Formula
The formula for converting frequency to wavelength is:
λ = v / f
Where:
- λ = Wavelength (in meters)
- v = Wave velocity (in meters per second, m/s)
- f = Frequency (in Hertz, Hz)
For example:
- For light in a vacuum, v=3×108 m/s (speed of light).
- For sound in air at 20°C, v=343 m/s
How to Calculate Wavelength from Frequency?
To calculate the wavelength of a wave, follow these steps:
- Identify the wave’s velocity (e.g., light in air, sound in water).
- Note the wave’s frequency in Hertz.
- Use the formula λ = v / f to compute the wavelength.
Frequency to Wavelength Conversion Table
Here’s a quick reference for common frequencies and their corresponding wavelengths for light in a vacuum:
Frequency (Hz) | Wavelength (m) |
---|---|
1×106 (1 MHz) | 300 m |
1×109 (1 GHz) | 0.3 m |
1×1014 | 3×10−6 m |
1×1015 | 3×10−7 m |
For sound waves, the velocity differs. Use specific values for the medium (e.g., sound in water at 20°C = 1482 m/s).
Frequency to Wavelength Calculator
Online tools like a frequency to wavelength calculator make this process quick and accurate. Enter the frequency and wave velocity, and the calculator instantly provides the wavelength.
Example:
Input:

Frequently Asked Questions
1. How do you calculate wavelength from frequency?
Use the formula λ = v / f, where v is the velocity of the wave and f is the frequency.
2. What is the wavelength of 100 Hz in air at 20°C?
With v = 343 m/s
λ=343 / 100 = 3.43 m
3. Why do light and sound have different wave velocities?
Light travels faster (e.g., 3×108 m/s) because it doesn’t require a medium, while sound depends on the medium’s properties.
