As we said, sound waves can be modeled with sine waves. The standard musical pitch is the A440 which means that the musical note A4 has a frequency of 440 Hz. So this note oscillates once every 0 seconds and it could be modeled using the curve y = sin(440-2nt) = sin(880nt). For each of the following musical notes, what would w be if we wanted to model the sound wave with y = sin(wt)? %3D (a) (i) C4, (261.63 Hz (iii) E4, (329.63 Hz) (v) G4, (392 Hz) (ii) D4, (293.66 Hz) (iv) F4, (349.23 Hz) (vi) Ba, (493.88 Hz)
