Question

1. a fisherman sees a fish in the water, but when he tries to grab it, the fish isnt where it appeared to be. which wave behavior is causing this visual error? explain why it causes the error.

Explanation:

The wave behavior causing the visual error is refraction. Light from the fish travels from water (higher optical density) to air (lower optical density) at the water - air interface. When light changes medium, it bends (refracts) away from the normal. Our eyes perceive the light as coming in a straight line, so we see a virtual image of the fish that is shallower (closer to the surface) than the actual fish's position.

Answer:

The wave behavior is refraction. Light from the fish refracts at the water - air boundary (bends away from normal as it moves from water to air). Our eyes follow the refracted light back in a straight line, creating a virtual image of the fish at a shallower position than its actual location, leading to the visual error.
