What is the relationship between frequency, wavelength and period?

Frequency (f), wavelength (λ) and period (T) are related by: λ = v/f and T = 1/f, where v is the speed of sound. Higher frequency means shorter wavelength and shorter period.

What is the audible frequency range?

Human hearing ranges from approximately 20 Hz to 20,000 Hz (20 kHz). Bass frequencies are below 250 Hz, midrange is 250 Hz to 4 kHz, and treble is above 4 kHz. Most people lose high-frequency sensitivity with age.

Does frequency change with temperature?

No — frequency is determined by the source. However, the speed of sound changes with temperature, which means the wavelength changes. At higher temperatures, the same frequency has a slightly longer wavelength.

How We Calculate This

Wavelength: λ = v / f

Period: T = 1 / f

Speed of sound: v = 331.3 + 0.606 × T(°C)

These three relationships allow conversion between any combination of frequency, wavelength and period.
