Question

A cylindrical tube (L = 125 cm) is resonant with a tuning fork of frequency 330 Hz. If it is filling by water then to get resonance again, minimum length of water column is(Vair=330m/s) -

Answer 1

Answer:

A cylindrical tube (L = 125 cm) is resonant with a tuning fork of frequency 330 Hz. If it is filling by water then to get resonance again, minimum length of water column is(Vair=330m/s) is 50 cm.

Therefore the student can get right ideas to step to calculate the right answer for the given values. Check the answer with no risk of it.

Explanation:

Answer 2

l=$\frac{1}{4}$m, $\frac{3}{4}$m

=25cm, 75cm.

$\therefore$ Minimum height of water column 

= 125 – 75

= 50 cm

$\therefore$Option A is correct answer.
