10. Joe the whistle maker knows that the maximum volume for a whistle will occur if the length of the whistle is exactly %% of the wavelength. If Joe must make a whistle that plays at a pitch of 320 Hz, how long will the whistle be? 11. How long is the wavelength of KAJA radio whose broadcast frequency is 97.1 MHz? (97.1 MHz =97,100,000 Hz and v = 300,000,000 m/s) 12. Using the velocity of sound at 343 m/s and given the frequencies of a piano scale, compute the wavelengths of that scale. Note Frequency Wavelength Note Frequency Wavelength C4 261.6 GA 392 DA 293.6 A4 440 E4 329.6 B4 493.9 F4 349.2 C5 523.2 13. What is the relationship of the frequencies of notes C4 and Cs? 14. What is the relationship of the wavelengths of notes C4 and Cs? 15. What happened to the wavelength as the frequency increased between notes C4 and C5
