* Light travels in straight lines: Light doesn't bend around corners on its own. It travels in a straight path, known as a ray of light.
* Reflection and Absorption: When light encounters a surface, like the inside of a pipe, it can be reflected or absorbed.
* Reflection in a Bent Pipe: In a bent pipe, the light rays hitting the inside surface of the bend are reflected at an angle. This means the light doesn't continue in the straight line needed to reach the other end of the pipe.
* No Direct Path: Since there's no direct straight line path for light to travel through the bend, none of the light that enters one end will reach the other.
In summary: Light doesn't bend around corners, and because of this, it can't travel through a bent pipe without some way to be redirected (like with mirrors).
