Wavelength to Frequency Formula

Share this post on:

A wave’s wavelength is the distance between two corresponding points on back-to-back waves. This can be measured between two wave crests or two wave troughs. In physics, the wavelength is usually represented by the Greek letter lambda (λ). A wave’s frequency is the number of times per second that it cycles. . Frequency is measured in Hertz or cycles per second. The frequency is often represented by the lowercase “f.”

How do you convert wavelength to frequency?
What is the formula to calculate frequency?

The velocity of a wave is usually represented by the letter “v.” The velocity can be calculated by multiplying the frequency by the wavelength.

velocity = frequency * wavelength
or
v = f * λ

Where:

  • λ = Photon wavelength, meters
  • v = Velocity (m/sc)
  • f = Frequency (Hz)
