The phase difference between the reflected waves

Question

A tuning fork generates sound waves with a frequency of 230 Hz. The waves travel in opposite directions along a hallway, are reflected by walls, and return. The hallway is 40.0 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 1.20 m long tube is closed at one end. At the open end there is a sound wave generator whose frequency can vary from 100Hz to 900Hz. The speed of sound is 343m/s.What is the lowest frequency of standing waves that can form in the tube?

Deep underwater, a sub moves through still water at a speed of 23 m/s. The sub sends out a 910 Hz sonar wave towards an underwater mountain. The wave reflects off the mountain and the sub detects the reflected wave. (The speed of sound in water is 1482 m/s.) Hint: this problem requires two parts. The sub is the source for the initial wave. The frequency does not change when the wave reflects from the mountain. For the reflected wave, the sub is the detector. What frequency does the sub detect for the reflected wave?
