Hole in the Bucket Questioning

This questioning would take place after the students saw the demonstration.

Q: What happened when you pointed the laser pointer into the hole in the bottle?

A: “the light went through the hole and followed the water down.”

Q: How does this compare to what happened when we used a flashlight?

A: “the light just spread out in all directions.”

Q: How would the behavior of a laser light be useful in the real world?

A: “they could use it to direct the light exactly where they want it to go like for medical purposes.”

Q: What if you don’t have a fluid involved, how else could you get the light to bend?

A: “use mirrors to direct the light.”

Q: Why would this work?

A: “because mirrors reflect light, you just have to move the mirrors at the right angle to get the light to move where you want it to go.”
