Question
You are playing a video game in which you're chained to one spot and you hear a dragon approaching. A light-activated switch that would open your chains is located in the sealed cavern shown in Figure PI 8.17. You have a laser cannon that you can fire through the small hole, but from your present position the laser beam will miss the switch. Fortunately, you possess a magical power that will let you momentarily fill with water either the cavern or the room in which you're chained. Can you use your power to release your chains in time to flee from the dragon? If so, what will you do? If not, why not?Explanation / Answer
fill the room with water
So that refrected angle in cavern is more than 20 degree and light bends upward to reach the switch.
as light goes from denser to rarer medium it diverts away from normal.
