A tuning fork of `512 H_(Z)` is used to produce resonance in a resonance tube expertiment. The level of water at first resonance is `30.7 cm` and at second resonance is `63.2 cm` . The error in calculating velocity of sound is
(a) `204.1 cm//s`
(b) `110 cm//s`
(c) `58 cm//s`
(d) `280 cm//s`

Explanation

To find the error in calculating the velocity of sound using the resonance tube experiment, we can follow these steps:

### Step 1: Determine the distance between the two resonances
The first resonance level is given as 30.7 cm, and the second resonance level is 63.2 cm. The distance between these two levels is calculated as:

\[ \text{Distance} = \text{Second Resonance} - \text{First Resonance} = 63.2 \, \text{cm} - 30.7 \, \text{cm} = 32.5 \, \text{cm} \]
