Explanation:
Explanation:
The eyes were positioned, such that the light rays coming from the coin were blocked by the rim of the cup.
By adding water to the cup, these same light rays from the coin are now refracted away from the normal, as it
travels from denser to a less dense medium
The normal is the line perpendicular to the surface separating the two media through which the light ray
travels. Other liquids with high refractive indices, usually the denser ones, may replace water in this case.
This phenomenon is the reason why some deep waters seem to look shallow

Answer:
Generally there is little or no refraction of light as it travels through air. However, when you pour water into the glass or jar in this activity the light is refracted ( bends ) and doesn't make it to your eyes which is why the coin seems to disappear.
