As Section discusses, sound waves diffract, or bend, around the edges of a doorway. Larger wavelengths diffract more than smaller wavelengths.

(a) The speed of sound is 343 m/s. With what speed would a 55.0-kg person have to move through a doorway to diffract to the same extent as a 128-Hz bass tone?

(b) At the speed calculated in part (a), how long (in years) would it take the person to move a distance of one meter?
