Question

To a bird flying in sky , the fish in water appears _ than is actual depth. Is it nearer or farther

Answer 1

Answer:

It appears nearer due to refraction of light rays from the rarer medium to the darker medium.

Answer 2

Answer:

The correct answer is nearer.

Explanation:

i) According to the laws of refraction, when a light ray is passing from a rarer medium to a denser medium, it refracts towards the boundary of the mediums.

ii) Since water is a medium of higher refractive index than air, the light rays are refracted towards the boundary and the objects are seen nearer when looked from the air.

iii) Hence, a fish in the water appears nearer to the bird in sky than its actual depth.
