I think the term you're looking for is resonance.

When you blow into the opening, it builds pressure until the back pressure is higher than the pressure coming in, so it blows back until the back pressure is lower than the input pressure. This happens at a frequency determined by the size of the bottle and the amount of pressure coming in, which creates an audible oscillation.

when you blow into the bottle the sound waves travel toward the bottom of the bottle from where they are reflected back. Now these incident and reflected waves combine to make stationary waves. These stationary waves comprise of nodes and antinodes and resonate at a certain frequency. If node is at the mouth of bottle then there is no sound and when antinode reaches mouth it produces sound.
