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, s
Distance sound traveled, m
Speed of sound, m/s
Air temperature outdoors, o
C
Table for Part 2
Frequency, f,
Hz
Length of air

Average
Air temperature indoors, o
C
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 the
earliest measurement of the speed of sound? When did that person make the measurement? How did he or she make the measurement?

2. Using the IV plots shown in Fig. 3 (and found in the reintroduction to PSpice) design a BJT
biasing circuit that results in the following parameters: VCE = 2 Vand ig = 40 μA. We
also require the power supply to be fixed at 5 Volts (this is where the load line intercepts
the iB =ic = 0 line). You may use the circuit shown in Example 1. Note that all resistor
values in Example 1 must be recalculated. Your solution for the base to ground and base
to collector resistors may not be unique.

Two charges are arranged on a number line. A positive 3C charge is located at zero. A negative 5C charge is located at x. There are the three regions on the number line.
I. Less than 0
II. Between 0 and x
III. Greater than x
In which region(s) could the electric field have a magnitude of zero?
