practice pre-test problems.

Remember:  Proper prior preparation prevents poor performance.

1.  B is 466.1 Hz, approximately.  Find the following frequencies:

a.  the next 2 octaves
b.  the 2 octaves below
c.  the C above (one semi-tone)
d.  the D above (3 semi-tones)

2.  Write your own Doppler effect problem and solve it - be sure to have a few different conditions.

3.  Consider a tube open on both ends, 0.4-m in length.  Find the relevant stuff for the first 3 harmonics:  wavelengths, frequencies, shapes.  Repeat for the same tube open on one end only.

4.  Graph the following:  y = 3cos(2x) - 5sin(3x).  Find the y value at x = 75 degrees.

5.  Review the speed of sound lab in your notes.
