Lab 4 Measuring the speed of sound
Report sheet
Name
Objective: To 1) measure the speed of sound outdoors, 2) capture a wave and measure its wavelength, and 3) demonstrate that the speed of sound depends on the medium through which it travels.
Data:
Table for Part 1
Time for sound to travel, sDistance sound traveled, mSpeed of sound, m/sAir temperature outdoors, oC
Table for Part 2
Frequency, f, Hz
Length of air column, L, cm
Length of air column, L, m
Wavelength, ë, m
Speed of sound, m/s
Average
Air temperature indoors, oC For both parts
Your expected speed of sound for Part 1, based on the air temperature, m/s Your expected speed of sound for Part 2, based on the air temperature, m/s Which of the methods in this experiment came closer to the expected speed of sound? Why might you expect one of these methods to be more or less accurate than the other?
Web extension
In your search of the internet, who do you think should get credit for theearliest measurement of the speed of sound?
When did that person make the measurement? How did he or she make the measurement?
