It is designated by the Greek letter lambda (λ). Difference between distances of propagating waves of some frequency. Wavelength is inversely proportional to frequency
Wavelength = Wave Speed / Frequency
Wavelength λ is computed using the formula
λ=v/f
where v is the phase speed of the wave and f is its frequency
E.g of Wave Length Sound Waves, Light
De Broglie Wavelength
Louis de Broglie postulated
λ=h/p
where h is Planck's constant, and p is the momentum of the particle.
The wavelengths of Sound frequencies audible to the human ear 20 Hz–20 kHz are between approximately 17 m and 17 mm respectively
