A) 884.4 m/s
B) 984.4 m/s
C) 1084.4 m/s
D) none of these
Correct Answer: A
Solution :
Distance between two consecutive nodes with air \[{{l}_{A}}=5cm.\] Distance between two consecutive nodes with hydrogen \[{{l}_{A}}=13.4cm.\] Velocity of sound in air = 330 m/s The velocity of sound is given by \[\upsilon H={{\upsilon }_{A}}\frac{{{l}_{H}}}{{{l}_{A}}}=330\times \frac{13.4}{5}\] \[=884.5m/s\]You need to login to perform this action.
