Physics 2306 Exam 1 Makeup (Arsenault) Spring 2006 1. A transverse wave traveling on a string is described by the expression y(x,t) = 3.2 mm sin (1.3 x / m - 10 t / s), where m=meters, mm=millimeters, and s=seconds . What is the frequency, f, of this wave? A 20  Hz F 1.59 Hz B 1.3 Hz G 2.42 Hz C 10 Hz H 20 Hz D 0.628 Hz I 0.314 Hz E 12 Hz J 314 Hz 2. For the wave in problem 1, what is the period, T, of the wave ? A 0.1 s F 0.159 s B 10 s G 7.69 s C 1.3 s H 76.9 s D 0.628 s I 769 s E 62.8 s J 1 s 3. For the wave in problem 1, what is the wavelength, , of the wave? A 1.3 m F 3.2 mm B 2.42 m G 0.13 m C 13 m H 13 mm D 0.769 m I 2.6 m E 7.69 m J 4.83 m 4. For the wave in problem 1, what is the speed, v, of the wave? A 7.69 m/s F 0.769 m/s B 3.14 m/s G 344 m/s C 1.3 m/s H 1 m/s D 10 m/s I 62.8 m/s E 13 m/s J 20 m/s 5. For the wave in problem 1, what is the direction the wave is traveling? A - x direction F - z direction B +x direction G it's not moving C up H cannot be determined D + y direction I - y direction E + z direction J down 2
Physics 2306 Exam 1 Makeup (Arsenault) Spring 2006 6. For the wave in problem 1, find the transverse velocity of the wave at time t=3s and position x=1m. A 13.2 mm/s F 29.1 mm/s B 10.2 mm/s G -10.2 mm/s C 65.8 mm/s H -62.1 mm/s D 31.4 mm/s I -19.4 mm/s E 0 J 3.14 mm/s 7. A pipe of length L=1m is open at both ends. Use v=344 m/s for the speed of sound. Find the frequency of the first over tone (second harmonic). A
