Atuning fork generates sound waves with a frequency of 240 hz. the waves travel in opposite directions along a hallway, are reflected by walls, and return. the hallway is 46.0 m long and the tuning fork is located 14.0 m from one end. what is the phase difference between the reflected waves(in degrees) when they meet at the tuning fork? the speed of sound in air is 343 m/s. [answer 68.2°] pls show steps
