| How does the frequency, oscillation period and wavelength change during the transition of sound from air to steel? The speed of sound in steel is 5000 m / s
The frequency and period of the oscillations remain unchanged.
The wavelength λ is determined by the formula:
λ = V / f, where V is the speed of sound, f is the frequency.
The speed of sound in the air is 330 m / s.
For the same frequency, we obtain the wavelengths in air and in steel:
λw = Vw / f;
λst = Vst / f;
λst = (Vst / f) / (Vw / f) = Vst / Vw = (5000 m / s) / (330 m / s) = 15.15.
Answer. When sound passes from air to steel, its wavelength increases 15.15 times.
