Question

Choose ALL the correct statements about beats. A) Typically favg >> fbeat B) Typically favg << fbeat C) When the two frequencies are nearly equal, we hear only the average oscillation frequency. D) The slow modulation causes the soft-loud-soft "beat" pattern we hear. E) Typically favg = fbeat F) When the two frequencies are nearly equal, we hear BOTH f1 and f2 independently. G) The slow modulation of frequency is described by a sinusoid.
