This is not exactly easy to understand. It can be explained by the fact that waves move slower in certain media - combined with the Huygens-Fresnel principle.
They bend at the interface between two media.
Refract
light travels in straight path and when speed of medium in which light travels change then it refract due to change in speed light rays bend and refract
No. The longer the wavelength the less the waves refract. Infrared bends even less.
The particles compress and refract, passing along the energy. It travels faster in mediums with particles that are more tightly packed eg. moves faster in metal as opposed to wood. Also, the more dense the air, the faster sound waves travel.

That happens right at the "interface" or "boundary" ... the exact place where the two media meet, and it's a different one on each side of that point.
the light rays hit the piece of glass and the surface of the glass causes it to refract
They refract
yes, sound is a wave. waves can be refracted.
They bend or refract
I will cause it to refract.
