The human ear is most sensitive to the frequency of 355 Hz, determine for this frequency the length of a sound wave in air at a temperature of 20 degrees, the speed of sound in air is 355 m / s
To find the value of the length of the specified sound wave, we will use the formula: λ = V / ν.
Constants: V – speed of sound in air at t = 20 ºС (by condition V = 355 m / s); ν is the frequency to which the human ear is most sensitive (ν = 355 Hz).
Calculation: λ = V / ν = 355/355 = 1 m.
Answer: The length of the specified sound wave is 1 meter.
