Vedclass · Answer

(A) Given: Frequency $(v) = 400 \, Hz$, Speed of sound $(V) = 340 \, m/s$, Number of vibrations $(n) = 16$.First, calculate the wavelength $(\lambda)$ of the sound wave using the formula: $\lambda = V / v$.$\lambda = 340 / 400 = 0.85 \, m$.The distance traveled by sound in one vibration is equal to its wavelength $(\lambda)$.Therefore, the total distance traveled in $16$ vibrations is $d = n 	imes \lambda$.$d = 16 	imes 0.85 = 13.6 \, m$.Thus, the sound travels $13.6 \, m$ when the tuning fork makes $16$ vibrations.

If the frequency of a tuning fork is $400 \, Hz$ and the speed of sound in air is $340 \, m/s$. Find how far sound travels when the tuning fork makes $16$ vibrations. (in $m$)
