13. 14. 15. 16. 17. e. نه ن نه فه C. A 60-vibration-per-second wave travels 30 meters in 1 second. Its frequency is: 30 hertz and it travels at 60 m/s 60 hertz and it travels at 30 m/s 1800 hertz and it travels at 2 m/s Not enough information to determine C. d. a. b. e. a. b. C. d. Assuming the velocity is constant, doubling the frequency of a sound wave, you will halve its: a. b. C. d. e. A Doppler effect occurs when a source of sound moves: Towards you Away from you Either away or towards you Not enough information to determine a. b. C. d. The pitch of a musical sound depends on the sound wave's: Speed Amplitude Frequency Wavelength None of these 18. The loudness of a musical sound is a measure of the sound wave's: A sound source is transmitting at 3,430 Hz. What is the corresponding wavelength if the air temperature is 20.0°C? (hint: think 2 formulas needed) a. Speed Amplitude Wavelength All of these None of these b. C. d. 0.10 m 0.10 ft 0.33 m Not enough information to determine a. Speed b. Amplitude Frequency d.
