Solution

The correct option is C $825 H z$
The in kundt's tube powder is collected where nodes are formed. The separation between nodes is given as

$d = \frac{λ}{2} = 20 c m$

$λ = 40 c m$

$f = \frac{c}{λ}$ $= \frac{330}{.4} = 825 H z$

Q. In Resonance tube experiment, if 400 Hz tuning fork is used, the first resonance occurs when length of air column in the tube is 19 cm. If the 400 Hz tuning fork is replaced by 1600 Hz tuning fork, then to get resonance, the water level in the tube should be further lowered by (take end correction = 1 cm)
