Question

The frequency of a tunning fork is 384 per second and velocity of sound in air is $352m/s$. How far the sound has traversed while fork completes 36 vibration

• A. 3m
• B. 13m
• C. 23m
• D. 33m

Answer 1

Answer: (D)

33m

(d) $\lambda =\frac{v}{n}=\frac{352}{384}$ during 1 vibration of fork sound will travel $\frac{352}{384}m$
during 36 vibration of fork sound will travel $\frac{352}{384}\times 36=33m$
