Relation Between Velocity And Wavelength

Wavelength is the measure of the length of a complete wave cycle. The velocity of a wave is the distance traveled by a point on the wave. In general, for any wave the relation between Velocity and Wavelength is proportionate. It is expressed through the wave velocity formula.

Velocity And Wavelength

For any given wave, the product of wavelength and frequency gives the velocity. It is mathematically given by wave velocity formula written as-

\(V=f\times \lambda\)


  • V is the velocity of the wave measure using m/s.
  • f is the frequency of the wave measured using Hz.
  • \( \lambda\) is the wavelength of the wave measured using m.

Velocity and Wavelength Relationtion

Amplitude, Frequency, wavelength, and velocity are the characteristic of any wave. For a constant frequency, the wavelength is directly proportional to velocity. Given by

\(V\propto \lambda\)


  • For a constant frequency, If the wavelength is doubled. The velocity of the wave will also double.
  • For a constant frequency, If the wavelength is made four times. The velocity of the wave will also be increased by four times.

Hope you understood the relation between wavelength and Velocity of a wave.
