Column of Air Resonance and the Velocity of Sound
This activity uses the resonance of a column of air to measure the velocity of sound.

Activity: Setup í Equipment
Glass Resonance Tube (Uniform Inside Diameter, With Scale Markings) Rubber Tube Reservoir Stand Low Frequency Generator (or Tuning Fork) Audio Measurement Setup (EA-200, graphic scientific calculator, data communication cable) Temperature Measurement Setup (EA-200, graphic scientific calculator, data communication cable, temperature probe)

Theory
Resonance is what occurs when one object vibrating at the same natural frequency of a second object causes the second object to vibrate. If you have two tuning forks of the same natural frequency located near each other and strike one of the tuning forks so begins vibrating, the other tuning fork will also vibrate even if you do not strike it. This is due to resonance. This activity uses a fixed-frequency sound source to produce resonance in a vertical resonance tube. The sound produced by the resonating column of air will sound louder than the sound produced by the sound source. The expressions below show the relationships between the length of the column of air and wavelength, and the velocity of sound and wavelength. The relationship between the velocity of sound and wavelength is called the basic equation.

    Brandon Physics, Period 1 23 May, 2014 Resonance Lab Purpose: To determine the speed of sound using the resonance method, temperature method and percent error. Hypothesis: If the temperature of the room’s 20 degrees C, then using the temperature method, the speed of sound is 344m/s. Vs – Vo + 0.6m/s T / C = 332 m/s + .6 m/s (20 C) / C = 344 m/s Conclusion: Using the resonance method the speed was 330 m/s. using the average temperature…

    INTRODUCTION: Magnetic Resonance Imaging(MRI) is a non invasive medical imaging method widely used in hospitals and in research. In year 1946 Felix Bloch of Standard /university and Edward Purcell of Harvard University made the first succesful nuclear magnetic resonance experiment to study chemical compounds, they were awarded the Nobel Prize for physics in 1952. In early 1980 's the first human magnetic resonance imaging( MRI) scanners became available, producing images of the inside of the…

    Magnetic resonance imaging (MRI) is a type of scan that produces detailed images of the inside of the body using radio waves and strong magnetic fields without using radiation. An MRI scanner is a large tube that contains powerful magnets. During the scan, you lie inside the tube. Almost any part of the body can be examined using an MRI, including the brain and spinal cord, bones and joints, heart and blood vessels, internal organs, and breasts. MRI scans are safe and painless. Almost everyone…

    History and Science Behind MRI: Open or Closed Case? Magnetic Resonance Imaging (MRI) has been called one of the most comprehensive and efficacious diagnostic imaging modalities in medical history. It became a viable clinical technique in 1982 and during its relatively short lifetime has become the primary imaging modality for investigations of the brain, spinal cord, spine, cancellous bone, and joints. It is widely used for the identification and staging of tumors, investigations of large…

    Chapter 4, page 1 4 Nuclear Magnetic Resonance Pieter Zeeman observed in 1896 the splitting of optical spectral lines in the field of an electromagnet. Since then, the splitting of energy levels proportional to an external magnetic field has been called the "Zeeman effect". The "Zeeman resonance effect" causes magnetic resonances which are classified under radio frequency spectroscopy (rf spectroscopy). In these resonances, the transitions between two branches of a single energy level…

    Nowadays, a Pitot tube would be of use as a speedometer on aeroplanes. It is also found useful in industries where velocity measurements are required, where an anemometer may not be the most efficient instrument to use. There are three types of pitot tubes: Pitot tubes, Static tubes, and Pitot-Static tubes. The simple pitot tube essentially consists of a tube bent at - usually - 90°, with an open end pointing directly towards the fluid flow. As the fluid flows in the tube, it becomes stagnant…
