Sound propagation and obstacles
What happens when sound hits an obstacle? The wave nature of sound is explained.
There are a number of ways a sound can behave when it hits an obstacle: refraction, reflection, dispersion, absorption, diffraction. All these possibilities arise ultimately because of the wave nature of sound.
