A) 356 m/s
B) 330 m/s
C) 343 m/s
D) 372 m/s
Correct Answer: A
Solution :
Here: Length of air column \[l=17.4\text{ }cm\] The frequency of fork \[v=512\text{ }Hz\] Speed of sound in air is \[\upsilon =4\text{ }v\text{ }l\] \[=4\times 512\times 0.174\] \[\approx 356\text{ }m/s\]You need to login to perform this action.
