Questions
Corresponding to given observation calculate speed of sound. Frequency of tuning fork =
| Resonance | Length from the water level (in cm) | |
| During falling | During rising | |
| First | 23.9 | 24.1 |
| Second | 73.9 | 74.1 |
detailed solution
Correct option is A
Mean length from the water level in first resonance isl1=23.9+24.12=24.0 cmSimilarly, mean length from the water level in second resonance isl2=73.9+74.12=74.0 cmSpeed of sound,v=2fl2-l1=2×340(0.740-0.240)=380 m/sTalk to our academic expert!

A tube of certain diameter and of length 48 cm is open at both ends. Its fundamental frequency of resonance is found to be 320 Hz. The velocity of sound in air is 320 m/s. One end of the tube is now closed, considering the effect of end correction, calculate the lowest frequency of resonance for the tube (in Hz).
