The shortest length of the air column in a resonance tube...
The shortest length of the air column in a resonance tube at resonance is 0.12m and the next resonance length is 0.37m. Calculate the frequency of vibration given that the speed of sound in air is 340m-1
1360Hz
694Hz
680Hz
34Hz
340Hz
Correct answer is C
f = v2(l2−l1)=3402(0.37−0.12)=340.5 = 680
