Answer 2

Path difference is spoken about when the questions tells you the waves are interfering. Remember constructive and destructive interference at when there is a difference of a whole number of wavelength or half wavelengths.

You should speak about stationary waves when given a single standing wave. Remember to talk about the difference in sounds at antibodies and nodes.
