Question

Height of a person standing on the land beside a river will appear ______________ to a fish inside the river.
(Note that the person is almost vertically above the fish)

• A. taller than the actual height
• B. shorter than the actual height
• C. same as the actual height
• D. exactly half of the actual height

Answer 1

The correct option is A taller than the actual height

When a light ray enters a denser medium from a rarer medium, it bends towards the normal. In the given case water is the denser medium and air is rarer medium. Reflected light from the person falls on water and after bending it comes to the fish. As fish see the straight path of light, height of the person will appear taller (y) to the fish than his actual height (x) as shown in the figure.
