Question

In a resonance column experiment the tube has diameter 6 cm, the tuning fork frequency is 480 Hz and the speed of sound in the room air is 350 m/s. The zero of the meter scale coincides with the top of the tube. The reading of the water level at first resonance is closest to

Options:

Answer:

A

Solution:

$l = \frac{v}{4 f} - 0.6 r$

$= \frac{350 \times 100}{4 \times 480} - 0.6 \times 3$

$= 18.23 - 1.8$

$= 16.4$ cm

TestHub · Accepted Answer

l = 4 f v ​ − 0.6 r = 4 × 480 350 × 100 ​ − 0.6 × 3 = 18.23 − 1.8 = 16.4 cm
