Question

1. How does the speed of the wave vary with the number of loops in the string? a. the greater the number of loops, the greater the speed b. the greater the number of loops, the lower the speed c. the fewer loops, the greater the speed d. the fewer loops, the lower the speed e. the wave speed does not vary with the number of loops, it is constant 2. If the vocal tract of a human is considered a closed tube 17 cm in length, what is the frequency of what would become the second harmonic? (Consider 340 m / s as the speed of sound) a) 1,500 Hz b) 15 Hz c) 150 Hz d) 15000 Hz e) 1500 Hz 3. The figure below shows different waves produced in different media. Which of the systems is vibrating at the fundamental frequency? a. none of the above and / or later b. "The whistle" (the whistle) c. "Vibrating rod" vibrating rod d. "Vibrating string" e. "The organ pipe" (organ pipe) 4. The Figure below shows the vibration pattern of a sound wave in a closed tube. If the length of the tube is 3.0 m, and the frequency of the vibration is 80 Hz, then the speed of sound is approximately equal to: a) 0.16 km/s d) 0.96 km/s b) 80 m/s e) 0.24 km/s c) 0.32 km/s
