- To which direction should you aim your high - power laser gun to shoot a fish in a lake? (You stand on the edge of the lake)
a. the position where you see the fish
b. higher than the position where you see the fish
c. lower than the position where you see the fish
d. depends on the speed of the fish
e. can not be determined
- Relevant Equations
- Snell's law
If we use a spear or gun with bullet, then we should aim lower than the position where we see the fish because due to refraction, the apparent position of the fish in the lake will be higher (nearer to the surface) than the actual position of the fish.
But if we use a laser gun, I think we should aim to the position where we see the fish because the laser will also be refracted towards normal line when entering the water.
So the answer is (a)
Am I correct?
Thanks
