Answer 2

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

1. When the bowl is empty, the rays of light coming from the coin are obstructed by the side of the bowl.

2. Hence, the coin is not visible when seen from one side of the bowl.

3. When water is poured in the bowl, the rays of light coming from the coin trave from water (denser medium) to air (rarer medium).

4. Hence, they bend away from the normal on refraction.

Therefore, the coin appears to be raised and becomes visible when observed from one side of the bowl.
