Answer 2

Yes, the coin is visible when we move away from the vessel after pouring water into it.

Explanation:

• When we place a coin in vessel and pour some water in the vessel we can see the coin because of the apparent depth.

• Apparent depth, when the light ray travels from rare medium (Air) to denser medium (Water) it bends away from the normal. Change in the medium we see the shift in the depth and the coin is visible.
