Ves On A String Virtual Lab Summary

A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules

-“The wave continues to travel for 4.0 m before stopping.” This sentence is wrong because we do not know if the wave will stop after it travelled for 4.0 m. The wave can continues moving after 4.0 m and the wavelength measures the distance between two adjacent locations in the disturbance.

Give 2 reasons why circular water waves decrease in amplitude as they travel away from the source?

The waves were beginning to be pulled back similar to that of a metal being attracted to the magnet. It was not stopping, the waves were continuously being pulled

“Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil left and right. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced leftwards and rightwards. In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.”

The graph axis was changed to % Transmittance vs. Wavenumbers. 7. The desired peaks were under a "value displaying line" and the graph, with the values, were printed. 8.

This answer is wrong because the wave propagates, not the medium. If the particles in the pulse travelled from one place to another then this would not be a wave. It would be translational or circular motion, but not oscillatory motion.

Resonance In an Air Column By Tara Sabzvari Introduction The purpose of the lab “Resonance In an Air Column” was to determine the resonant lengths of an air column for a given frequency of sound by finding the local speed of sound. The experiment was focused on the resonant lengths for a fixed-free end medium as the air column was closed on one end and open in the other. In addition, waves reflect off both fixed and open ends of a medium, in this case an air column. Furthermore, resonance is the condition in which the frequency of a wave equals the resonant frequency of the wave’s medium, which is one of the objectives of this lab.

If the above minor, surface error, and style points are addressed, I recommend this paper for publication. It is directly useful to an audience of undergraduates of physics and sufficiently supports both the existence of standing waves as well as wave interference. Additionally, the paper does a fairly good job of describing the experimental setup and logic in measurements. This lends to the reproducibility of the experiment and future modifications and

The vast blue ocean sits in peace; the water looking as if it is glass. Not a single ripple disturbs the tranquility of the bright blue ocean. Then instantaneously, without warning, a large destroyer ship that goes by the name of the USS Theodore E Chandler cuts through the ocean, sending large waves to roll for miles and miles. A single large wave sweeps with ease through the glassy water, disturbing the composure of the ocean. The wave starts extremely large, but over time it shall diminish to a single wavelet. As time goes on, the wave become less of its original form, yet it travels a journey. As the wave glides over the immense ocean, it will undergo many experiences, and challenges. Over time the wave will lessen to almost nothing, but from almost nothing another wave will emerge; taking a path of its own. The first wave will experience a great journey, gathering wisdom

What behaviors do air vibrations cause? They cause a Standing wave. A standing wave is the result of the wave reflecting off the end of the tube and interfering with itself. Vibration inside a tube forms a standing wave. When sound is produced in an instrument by blowing into it, allows

The red bar on the left acts as the driving piston. If it moves in a sinusoidal manner from left to right, then the wave that is produced will be a sinusoidal wave. Since the wave is sinusoidal, the wavelength, amplitude and frequency are constant. This is seen in nature as a tuning fork, which produces a periodic sound wave. In a one dimensional tube as shown above, each particle undergoes simple harmonic motion. The volume that is contained in one wavelength also undergoes this same motion. We can represent the displacement of this volume as:

Work from the thickest string to thinnest thin string. You must adjust the order in standard

If the string expands and its length increases, as described before, the frequency produced will change. Conduct the experiment in an air conditioned room to keep the temperature constant Apparatus Newton Meter, 100N maximum reading Tape Measure, 3 Meters Classical Guitar
