Question

When trying to catch a fish, should a pelican dive into the water horizontally in front of or behind the image of the fish it sees?

• A. In front of image
• B. Behind the image
• C. Cannot be inferred
• D. None

Answer 1

The correct option is A In front of image

By law of refraction, we know that light bends away from the normal when it enters the air so pelican has to dive in front of the image of fish in horizontally.

When the light leaves the water from the fish it bends away from the normal which makes the fish appear to be nearer to the surface.
