What beat frequency does he observe

Reference no: EM13488108

A student holds a tuning fork oscillating at 256 Hz. He walks toward a wall at a constant speed of 1.20 m/s.

(a) What beat frequency does he observe between the tuning fork and its echo? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.

(b) How fast must he walk away from the wall to observe a beat frequency of 5.60 Hz?
