The estimate errors on the measured speed of the sound are between 025% and 125% which show that the method presented above to measure the speed of sound is quite accurate it does not involve large errors and give a quite good value for the experimental speed of sound. While this speed may seem fast by human standards (the fastest humans can sprint at approximately 11 m/s and highway speeds are approximately 30 m/s), the speed of a sound wave is slow in comparison to the speed of a light wave. Discovering the speed of sound in air continued 2 21 inn scientific nc a ights eserved a standing wave is a pattern that results when two waves of the same frequency, wavelength, and amplitude travel in opposite.
The objective of this lab is to learn one method to accurately measure the speed of sound in air we’ll use a microphone, the labquest lab interface, and a computer to record a sound pulse and its echo in a cardboard tube. 1 the problem statement, all variables and given/known data if you had data from a lot of different frequencies, how could you use a slope to find the speed of sound. Title: speed of sound purpose to determine the speed of sound in air concept sound moves through air because a vibrating source produces frequent variations in air pressure.
Physics 215 – experiment 7 the speed of sound in air 3 procedure 1 lift the water container to a height such that the sound tube almost fills with. Computer 33 physics with vernier 33 - 1 speed of sound compared to most things you study in the physics lab, sound waves travel very fast it is fast. View lab report - speed of sound lab report from physics 2a at pasadena city college lab 12: speed of sound david liu april 29, 2015 individual report physics 2a group 3 group members: mohammad.
Speed of sound lab measuring the speed of sound and air using a pulse-echo technique purpose to determine the speed of sound in air using the pulse-echo experiment procedure, and comparing it to the predicted speed of sound in air using the measured air temperature of the classroom. Speed of sound lab using standing waves in a tube closed at one end. The goal of this lab was to explore a multitude of ways in which to find the speed of sound through three methods, two experimental and one theoretical, a good understanding of a few ways to calculate the speed of sound was created. This is a simulation of a standard physics demonstration to measure the speed of sound in air a vibrating tuning fork is held above a tube - the tube has some water in it, and the level of the water in the tube can be adjusted this gives a column of air in the tube, between the top of the water . Compared to most things you study in the physics lab, sound waves travel very fast it is fast enough that measuring the speed of sound is a technical challenge one method you could use would be to time an echo for example, if you were in an open field with a large building a quarter of a .
University of tennessee chattanooga physics 1030l lab 2/06/2013 physics 1030l laboratory measuring the speed of sound in air using a resonance tube objective: the purpose of this experiment is to measure the speed of sound in air by exploiting standing wave and resonance effects in longitudinal . V is the speed of sound and t is the temperature of the air one thing to keep in mind is that this formula finds the average speed of sound for any given temperature the speed of sound is also affected by other factors such as humidity and air pressure. I will go through a process that will allow you to determine the speed sound travels this is a classic physics lab that in the past would have required lots of expensive equipment the only expensive equipment involved here is a computer with a microphone input which by itself can be expensive . The objective of this lab is to measure the speed of a sound wave in the air and compare it to its theoretical value figure 3 : examples of resonance for n = 1, 2, and 3 according to the theory, the speed of sound in air depends upon the temperature of the air through the following relationship.
Speed of sound lab objective: to measure the speed of sound using the concept of resonance to determine what, if any, effect varying the frequency of a sound wave has on the speed of that sound wave to determine what, if any, effect varying the temperature of air has on the speed of a sound wave. Speed of sound lab purpose: determine the speed of sound in air by using resonant air columns apparatus: two or three tuning forks of frequency greater than 256 hz large measuring cylinder, water, metre stick, , long tubes (red & clear), temperature reading from thermostat (or thermometer). In this lab we focused primarily on using standing sound waves (compressional waves) created by tuning forks in order to determine the speed of sound in air in a tube when it reaches resonance. Speed of sound lab purpose: the purpose of this lab is to determine the speed of sound using the principle of resonance materials: resonance tube, large graduated cylinder, meter stick, and tuning forks.
1 introduction there are many ways to determine the speed of sound the method we will use in this lab is both fairly straight forward and the equipment needed is fairly minimal. : the speed of sound in air should be given by the equation v= 331+06 (t), where t is the temperature of the air, in degrees celsius conclusion by jack reynolds, olivio ott, amal karesh , armando hernandez. How fast does sound travel help your child figure out the physics of sound waves with this informative worksheet he'll learn about the speed of sound through different materials, and even try a tough math challenge. View notes - speed of sound lab from phys 101l/102l at university of south carolina speed of sound lab cycle 4 abstract the purpose of this lab was to determine the speed of sound in air.
