JEE Physics General, Speed of sound using resonance column, , , , , , ,

The speed of sound in air can be determined using a resonance column. Here are the steps:

  1. Set up a resonance column: A resonance column is a long, hollow tube filled with a liquid, usually water. The tube should be vertical and have a height of at least 1 meter. A tuning fork can also be used to create the sound waves.
  2. Measure the height of the air column: With the tuning fork not touching the column, adjust the water level in the tube until it is a few centimeters from the top. Measure the height of the air column above the water level using a ruler.
  3. Strike the tuning fork: Hold the tuning fork over the mouth of the column and strike it. The sound waves will travel down the tube and reflect off the water’s surface.
  4. Measure the new height of the air column: As the sound waves reflect back and forth between the water surface and the closed end of the column, a standing wave pattern will be created. The air column will resonate at certain frequencies, causing the water level to oscillate up and down. Adjust the water level until the oscillation is at a maximum and measure the new height of the air column.
  5. Calculate the speed of sound: The speed of sound can be calculated using the formula:

speed of sound = 2 x frequency x height of air column

Where frequency is the frequency of the tuning fork and the height of the air column is the difference between the heights measured in steps 2 and 4.

Note: The temperature of the air inside the column can affect the speed of sound. Therefore, it is important to measure the temperature of the air and apply a correction factor to the calculation if necessary.

  2. Measure the height of the air column: Adjust the water level in the tube until it is a few centimeters from the top, and measure the height of the air column above the water level.
  3. Determine the frequency of the tuning fork: The frequency of the tuning fork can be determined using a frequency counter or by referring to the manufacturer’s specifications.
  4. Measure the new height of the air column: Strike the tuning fork and hold it over the mouth of the column. Adjust the water level until the oscillation of the water level is at a maximum, and measure the new height of the air column.
  5. Calculate the speed of sound: Using the formula:

speed of sound = 2 x frequency x height of air column

Calculate the speed of sound in meters per second, where the frequency of the tuning fork is measured in Hertz (Hz) and the height of the air column is measured in meters (m).

Note: Ensure that the temperature of the air inside the column is measured and the speed of sound calculation is corrected if necessary.

Case Study on General Speed of sound using resonance column

One example of a case study involving the General Speed of sound using resonance column is the study conducted by a group of undergraduate physics students at a university. The purpose of the study was to determine the speed of sound in air at room temperature using a resonance column and a tuning fork.

The students set up the resonance column by filling it with water and adjusting the water level to a few centimeters from the top. They then measured the height of the air column above the water level and determined the frequency of the tuning fork to be 512 Hz using a frequency counter.

The experiment is relatively simple and provides an accurate method for measuring the speed of sound, which can be useful in a variety of scientific and engineering applications.

White paper on General Speed of sound using resonance column

Introduction

Sound waves are longitudinal waves that require a medium for propagation. The speed of sound in a given medium depends on the temperature, pressure, and density of the medium. In air, the speed of sound is approximately 343 m/s at standard temperature and pressure. Accurate measurement of the speed of sound is important in various fields such as physics, engineering, and acoustics. One method for measuring the speed of sound in air is through the use of a resonance column and a tuning fork. This white paper provides an overview of the General Speed of sound using resonance column.

Experimental Setup

A resonance column is a hollow tube filled with water. The height of the air column above the water level can be adjusted by adding or removing water. A tuning fork is a metal fork with two prongs that vibrate at a specific frequency when struck. To measure the speed of sound using a resonance column, a tuning fork with a known frequency is held above the mouth of the column and struck with a rubber mallet. The tuning fork creates sound waves that travel down the column and reflect off the surface of the water, creating a standing wave pattern. The frequency of the sound wave is adjusted by changing the height of the air column until the standing wave pattern is at a maximum.

Calculation of Speed of Sound

The speed of sound in air can be calculated using the formula:

Speed of sound = 2 x frequency x height of air column

Where the frequency of the tuning fork is measured in Hertz (Hz) and the height of the air column is measured in meters (m). The frequency of the tuning fork can be determined using a frequency counter or by referring to the manufacturer’s specifications. The height of the air column can be measured using a ruler or a measuring tape.

Corrections and Sources of Error

Several corrections may need to be applied to the speed of sound calculation. The temperature of the air inside the column can affect the speed of sound, and a correction factor can be applied using the following formula:

Speed of sound at room temperature = Speed of sound x sqrt(T / 293)

Where T is the temperature in Kelvin and 293 K is the standard temperature at which the speed of sound is defined as 343 m/s. Other sources of error may include variations in the frequency of the tuning fork, inaccuracies in the measurement of the height of the air column, and variations in the temperature and pressure of the room.

Conclusion

The General Speed of sound using resonance column provides an accurate method for measuring the speed of sound in air. The experiment is relatively simple and can be conducted using basic laboratory equipment. The use of a tuning fork and a resonance column can be applied in various fields such as physics, engineering, and acoustics to determine the speed of sound in different mediums. Corrections and sources of error must be taken into account to ensure accurate results.
