) and is not affected by the frequency of the sound. The relationship between the speed of sound (v), its frequency (f), and its wavelength (λ) is given by the equation: v = f * λ This means that for a given speed of sound, if the frequency increases, the Show more…

Two tuning forks with frequencies of $256 \mathrm{Hz}$ and $512 \mathrm{Hz}$ are struck. Which of the sounds will move faster through the air?
The 512 Hz tuning fork has twice the frequency of the 256 Hz tuning fork. How does the wavelength of the 512 Hz tuning fork compare to the wavelength of the 256 Hz tuning fork?

Two identical tuning forks vibrating at the same frequency $256 \mathrm{~Hz}$ are kept fixed at some distance apart. A listener runs between the forks at a speed of $3 \cdot 0 \mathrm{~m} / \mathrm{s}$ so that he approaches one tuning fork and recedes from the other (figure $16-\mathrm{E} 10$ ). Find the beat frequency observed by the listener. Speed of sound in air $=332 \mathrm{~m} / \mathrm{s}$
