Wavelength

WAVE LENGTH OF A SINE WAVE

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
