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

Yes, it does refract light.
No, opaque substances can NOT refract light. It is impossible to refract light if it is blocking it's path.
the light rays hit the piece of glass and the surface of the glass causes it to refract

This is because the Earth's atmosphere has many layers which causes the rays of light coming from the stars to refract. This gives the effect that stars twinkle. The air around the moon does not have layers so the rays from the stars do not refract, and thus do not twinkle.
a prism can be used to refract wight light
Clear glass does refract light when light passes from another medium like water to clear glass. But there is an exception. If the ray of light were to pass through water and hit the clear glass straight or at 90 Degrees to the surface, then clear glass does not refract the light.
