The frequency range of the grand piano is from 9 to 90000 Hz. Find the range of sound waves in the air
| October 8, 2021 | education
v1 = 9 Hz.
v2 = 90,000 Hz.
Vsv = 340 m / s.
λ1 -?
λ2 -?
The frequency of the sound wave v is related to the wavelength λ by the formula: Vsv = v * λ, where Vsv is the speed of the sound wave.
λ1 = Vev / v1.
λ1 = 340 m / s / 9 Hz = 37.7 m.
λ2 = Vev / v2.
λ2 = 340 m / s / 90,000 Hz = 0.0037 m.
Answer: λ1 = 37.7 m, λ2 = 0.0037 m.
