Light travels in straight lines, like a pencil. When it hits something, like a wall or a corner, it can’t go around, it just keeps going straight. That’s why we don’t see around corners.
Examples
- Light travels in straight lines, so it can’t bend around a wall.
- We see what’s in front of us, not behind it, like looking through a door frame.
- When light hits a surface, it either reflects or goes through it, but doesn’t go around.
