Question

If, while standing on a riverbank, you wish to spear a fish beneath the water surface in front of you, should you aim above, below, or directly at the observed fish to make a direct hit? If, instead, you zap the fish with a laser, should you aim above, below, or directly at the observed fish? Defend your answers. You can draw a picture if you wish.

Read the selected scripture and, in your response to the prompt, discuss how the scripture relates to the discussion topic.

Again Jesus spoke to them, saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.” John 8:12

Answer 1

When we observe the fish, the rays reflecting from the fish undergoes refraction at the surface of the water and air and bends at a certain angle. Thus the fish appears at less depth than the real depth of the fish. Thus we should aim below the observed fish to make a direct hit.

However, the laser does not undergo refraction and if we zap the fish with a laser, it would point the real position of the fish and we should aim directly at the observed fish.
