The correct Answer is:
To find the speed of sound in air using the resonance tube experiment, we can follow these steps: ### Step 1: Understand the relationship between frequency, speed, and wavelength The fundamental frequency of a closed organ pipe can be expressed using the formula: \[ f = \frac{V}{4L} \] where: - \( f \) is the frequency (in Hz), - \( V \) is the speed of sound (in m/s), - \( L \) is the length of the air column (in meters). ### Step 2: Convert the given values to appropriate units The minimum length of the air column is given as 16 cm. We need to convert this to meters: \[ L = 16 \text{ cm} = 0.16 \text{ m} \] The frequency is given as: \[ f = 480 \text{ Hz} \] ### Step 3: Calculate the end correction The end correction \( e \) for a closed pipe is given by: \[ e = 0.6 \times R \] where \( R \) is the radius of the pipe. The diameter of the pipe is given as 5 cm, so the radius is: \[ R = \frac{5 \text{ cm}}{2} = 2.5 \text{ cm} = 0.025 \text{ m} \] Now, we can calculate the end correction: \[ e = 0.6 \times 0.025 \text{ m} = 0.015 \text{ m} \] ### Step 4: Adjust the length of the air column The effective length \( L' \) of the air column, taking into account the end correction, is: \[ L' = L + e = 0.16 \text{ m} + 0.015 \text{ m} = 0.175 \text{ m} \] ### Step 5: Substitute the values into the frequency formula Now we can rearrange the formula for speed \( V \): \[ V = 4Lf \] Substituting the values we have: \[ V = 4 \times 0.175 \text{ m} \times 480 \text{ Hz} \] ### Step 6: Calculate the speed of sound Calculating this gives: \[ V = 4 \times 0.175 \times 480 = 336 \text{ m/s} \] ### Final Answer The speed of sound in the air column at room temperature is approximately: \[ V \approx 336 \text{ m/s} \] ---
