Determine the sound wavelength of a human voice at a pitch of 680 Hz. (The speed of sound is considered equal to 340 m / s.)
Given: ν (vibration frequency of the human voice) = 680 Hz.
Constant values: by condition we take V (speed of sound in air) = 340 m / s.
The length of a sound wave of a human voice will be equal to the ratio of its propagation speed and a given vibration frequency: λ = V / ν.
Calculation: λ = 340/680 = 0.5 m (50 cm).
Answer: The sound wavelength of the human voice is 50 centimeters.
