Refraction fish in water
WebRefraction and fishermen Question: Why do fishermen aim at the tail of the fish while fishing with a spear? Answer: This is all to do with the refraction of light and real and apparent … WebApparent depth of an Object. Example: A bird in air is at a height y from the surface of water. A fish is at a depth x below the surface of water. The refractive index of water is μ. Find the apparent distance of fish from the bird. Solution: So, apparent distance of fish from the bird: = μ ary + μ waerx = 1y+ μx=y+ μx.
