Lab: Speed of Sound

Essential Question Asked:

How does the speed of sound differ between metals and gases?

Background Information:

The speed of sound is gauged by distance over time (distance/time).

Certain aspects that can change or affect the speed of sound would include the density of the item through which the sound is traveling. Continuing on with that concept, when sound is traveling through the air at a certain speed, factors may include the temperature, dampness and humidity of the air, and the density of the air as well.

The speed of sound through the air is measured to be to be 343 meters per second. The speed of sound

Repeat steps 2-4, and also calculate the average time for 200 meters.

IX. To calculate the speed of the sound, the distance should divide the time.

Process Number two: finding the speed of sound through the metal rod.

I. Connect the Vernier Lab microphones to the LoggerPro program.

II. Place the Vernier Lab microphones precisely two meters from each other.

III. Gently tap the metal weight at the tip of the metal rod, allowing a sound to be generated.

IV. LoggerPro would gather the time that it took for the sound to reach the microphones.

V. Calculate the difference between the two times that were recorded by the Vernier Lab microphones. This difference is the amount of time it took the sound to travel between the two microphones.

VI. Repeat steps 3-5 until there is a total of three different recordings. Calculate the average.

VII. Change the distance between the two microphones to three meters.

VIII. Repeat steps 3-5 and calculate the average.

IX. Change the distance between the two microphones to four meters.

X. Repeat steps 3-5 and calculate the average.

XI. Take the average time for all three distances, and divide the time by the distance. This will lead to three different speeds of sound.

XII. Calculate the average speed of
