In an experiment to determine the velocity of sound in air using resonance column apparature, the first and resonating length measured to be 25.4 and 78.5cm respectively. Calculate the velocity of sound in air and the end correction of frequency of the turning fork is 320Hz.

Explanation

To solve the problem of determining the velocity of sound in air using the resonance column apparatus, we will follow these steps:

### Step 1: Convert the lengths from centimeters to meters
We have two lengths:
- First resonating length \( L_1 = 25.4 \, \text{cm} \)
- Second resonating length \( L_2 = 78.5 \, \text{cm} \)

Convert these lengths to meters:
