When the wavelength is bigger than an obstacle, then the sound waves bend around the obstacle.
so why
I can't imagine this at all
I read this page and watched the animations of it but it doesn't tell me the answer

reflection of sound takes place when the difference in the speed of the sound between two media is great,while refraction takes place when the difference in the speed of the sound between two media is small
why?
