Frequency and Wavelength Calculator
A Frequency and Wavelength Calculator is a tool that helps determine the relationship between the frequency, wavelength, and speed of a wave — often for electromagnetic waves like light, radio waves, or sound waves. It's based on the fundamental wave equation:
Where:
v = Wave speed (like the speed of light in a vacuum,
3×108m/s, or the speed of sound in air)
f = Frequency of the wave (in Hertz, Hz)
λ = Wavelength (in meters, m)
Depending on what you know, the calculator can solve for any one of the three variables:
Frequency:
f=
λ/
v
Wavelength: λ = f/ v
Wave Speed: f *λ
For example, for a radio wave with a frequency of 100 MHz:
The calculator is useful for applications in physics, engineering, telecommunications, and audio tech.
