You are designing a new piece of fishing equipment that will allow you to catch a fish from the surface. You know that water refracts (bends) light, but in order to properly program your device, you need to know by what angle water refracts (bends) light. Describe an experiment you would conduct to determine the angle at which water refracts (bends) light.
