A string vibrates in the fundamental, producing the note A (440 Hz). Suppose the speed of sound in the air could be suddenly doubled ( but the string is left unchanged) What would you HEAR? A) Same pitch (440 Hz) B) Lower pitch C) Higher pitch, but not double D) Double pitch = one octave higher E) ??
