A tuning fork generates sound waves with a frequency of 232 Hz. The waves travel in opposite directions along a hallway, are reflected by walls, and return. The hallway is 42.0 m long and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected waves when they meet at the tuning fork? The speed of sound in air is 343 m/s.

A tuning fork generates sound waves with a frequency of 252 Hz. The waves travel in opposite directions along a hallway, are reflected by walls, and return. The hallway is 47.0 m long and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected waves when they meet at the tuning fork? The speed of sound in air is 343 m/s. (I got 304.9 and it says "Your response is within 10%...
