The speed of sound in sea water, where you can also do this experiment, providing you have a big body of water, waterproof equipment, and are making sure you aren't deafening whales, is 1500. Practical physics » molecules in motion » measuring the speed of sound 3 search home topics astronomy this is because of the time taken for the signal from the loudspeaker to travel through the air to the microphone moved by the signal on the screen when the microphone is moved 1 metre using the corresponding time, the speed of. Measurement of speed of sound rameez ahmad physics lab,sse,lums objectives to develop a freshmen year lab experiment student will learn to verify speed of sound reminder : speed of sound in air (at 29315 k / 20 c) is 3432m/s audacity interface stereo option. Divide the distance (in metres) by the average time measured (in seconds) to calculate the speed of the sound for example we stood 50m from the wall that provided the echo, so the total distance travelled by the sound was 50x20 = 1000 metres.

A tube that is open at one end and closed at the other by a movable piston is used in an experiment to measure the speed of sound in air, as shown in the figure below, on a warm day in a lab with no air-conditioning a 376 hz tuning fork is held at the open end resonance is heard when the piston is at a distance d1 = 232 cm from the open end and again when it is at a distance d2 = 683 cm. I did an experiment in class to determine the speed of sound i used the speed of sound in air equation with the room temp at 28°c which was calculated at 3486m/s however when doing the experiment i got 329m/s. This has on air column resonance 3 describe how a resonance tube can be used to measure the speed of sound in air introduction as an application of resonance, in this experiment the speed of sound in air will be determined by driving an air column in resonance.

The speed of sound in air is about 320 m/s in water it is 1500 m/s and in steel it is 6000 m/s the reason for the difference in the speed of sound in the different materials is that sound waves are carried by molecules banging into each other and in air the molecules are far apart and not held together firmly. Thus the speed of sound, v = 2s/t in the first case teaching notes 1 students are far more likely to grasp and to remember how to get the estimated speed of sound if you can arrange for them to undertake this experiment in pairs. 328 describe an experiment to measure the speed of sound in air measure the distance between two places, have a sound made in one place, as soon as you see the sound has been made start a stop watch, as soon as you hear the sound made stop the stopwatch. The speed of sound in air: an at-home experiment experiment that students can do at home to determine the speed of sound in air a set of audio files with selected frequencies is first. The speed of sound although sound travels quite fast, it is still possible to calculate its speed in air to do this, the time it takes a sound to travel a measured distance must be recorded.

So sound has travelled the extra 58 m in 017 s, giving a speed of 340 m/s time of flight: light vs sound sound is much slower than light: 340 m/s vs 300,000,000 m/s. The speed of a sound wave in air depends upon the properties of the air, mostly the temperature, and to a lesser degree, the humidity humidity is the result of water vapor being present in air like any liquid, water has a tendency to evaporate. Speed of sound in air is given by the equation where r is the gas constant, m is the molar mass of air and t is the kelvin temperature use your measured value of speed of sound and the room temperature to obtain a value for the speed of sound in air at (a) 0oc, (b) at 100oc.

Measure the speed of sound in a metal rod one employs a fast timer to measure mode of a freely suspending singing rod, and the speed is calculated using v = f λ the measurement of the speed of sound in a solid rod is one of the most difficult demonstrations and through air was measured since the speed of sound in air was known, by. Trial no242 0003687 0203 0002083 001) 09 m/s (4sf) line of maximum fit • 0 512304 0001953 step 4: finding the value for the speed of sound using the lines of best002193 0 the equation being used for calculating the speed of sound is t=4h/v the speed of sound can be calculated if t is plotted as the y axis002930 0. 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. Students use a microphone and vernier labquest to record the sound of a finger-snap echo in a 1-2 meter cardboard tube students measure the time for the echo to return to the microphone, and measure the length of the tube.

The speed of sound note this manual describes the laboratory experiment used during the 1996 - 1997 academic year significant changes have been made since then, and the manual used during the current academic year is in not available yet on the web. In this experiment you will use this technique with a microphone connected to use this technique to measure the speed of sound in air at different temperatures 5 develop a method for measuring the speed of sound in a medium that is not a gas title: microsoft word - 33 speed of sound lq author: anro. The speed of sound in air is approx 340 m s-1, so we can generate velocities that are sufficiently large to produce modest but quite measurable doppler shifts in these experiments we use a computer with internal microphone to record the sound from a moving source. Tof air 1 calculate the speed of sound from eq(6) 2 propagate the uncertainty in this quantity and calculate u{v} 3 compare this range with the theoretical range of values calculated in 2d and 2e above.
