Consider the two waves shown in Fig. 12–
qm*;5zxr8xij l; - 5obgch.b n:ipds931. Each wave can be thought of as a superposition of two sound waves with slightly different frequencies
micdog *sb9:pxn ;5lhx r.z- jq8i5b;, as in Fig. 12–18. In which of the waves, (a) or (b), are the two component frequencies farther apart? Explain.
