A student was walking through a shallow, slow-moving river searching for stones. The student observed a unique looking stone, but when she initially went to reach for the stone, it wasn't in the spot it appeared through the water. Why wasn't she able to grab the rock the first time?

• The path of light can bend through water.

• Light waves always travel in straight lines.

• The path of light reflected off the surface of the water.

• Light waves are transverse waves and sound waves are longitudinal.
