प्रश्न
Why does a fisherman aim at the tail of fish during spearfishing?
Advertisements
उत्तर
Due to refraction, when the rays travel from water to air, the apparent image of the fish is formed at a higher level and ahead of the actual position of fish. Thus, when the fisherman aims at the tail of the apparent image of fish, his spear hits the head of actual fish.
