interfere with each other
When a wave bends around an obstacle, it is called diffraction.
with diffraction
Diffraction is phenomena that occurs when a wave encounters an obstacle. This happens when a wave reaches an obstacle that is comparable in size to it.
I believe you are referring to Refraction.
Yes it seems so. As per Huygen's priciple the secondary wavelets would travel even beyond the edges.

The sound wave has undergone refraction.
Bends and spreads out.When waves of any kind, sound, light electromagnetic radiation hit a gap in a barrier that is on the same scale as the wavelength then diffraction will occur. Diffraction is the bending of the wave and this appears as circular waves when we observe this effect with water.A common diffraction grating can be seen on a CD or DVD. The light spreads and we see this as different colours.

If the wave travels through a slit or hole that is is small with respect to the wavelength, then the wave can bend quite a bit.
