Wave Mechanics Question 845
Question: The frequency of a tunning fork is 384 per second and velocity of sound in air is 352 m/s. How far the sound has traversed while fork completes 36 vibration
[KCET 2001]
Options:
A) 3 m
B) 13 m
C) 23 m
D) 33 m
Show Answer
Answer:
Correct Answer: D
Solution:
$ \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=33 $
$ m $
