Calculating…

This calculator uses the wavelength equation to solve for wavelength, velocity, or frequency when two of the three variables are known.

The Wavelength Equation

λ = v / f

Where:

  • λ = wavelength (in meters)
  • v = velocity (in meters per second)
  • f = frequency (in hertz)

Example Calculation

Suppose a bell rings with a frequency of 130 Hz, and the speed of sound in air is 343 m/s. The wavelength would be:

λ = 343 m/s / 130 Hz = 2.64 meters

Common Velocity Values

Speed of Light 299,792,458 m/s
Speed of Sound in Air (20°C) 343 m/s
Speed of Sound in Water (20°C) 1,481 m/s
