Question

The bottom of a pond appears raised Give reason

Answer 1

Answer:

It occurs due to phenomenon of light called as refraction.

Explanation:

While seeing into the pond, light travels from denser medium(water) to rarer medium(air) after reflecting from the surface. The light rays pass through the air-water interface, they get bent due to refraction. The light rays are bent away from the normal making us perceive the bottom of the pond or tank as raised.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

1. The rays of light coming from the bottom of a pond bend away from the normal as they travel from water (denser medium) to air (rarer medium).

2. Hence, they appear to come from a point above the actual point from which they come.

Therefore, the bottom of a pond appears raised.
