Question

An expert archer tries to shoot an arrow into a target lying at the bottom of a shallow pool, even though the water does not change the direction of the arrow, the archer misses the mark by several inches. What interaction of light and water caused the archer to miss?

Answer 1

The light reflected back to the archer from the target has a different angle of incidence than if the target were in the air.

Answer 2
