Answer:
True.
Explanation:
If a coin is kept in an empty glass container such that it is not visible to us, but if water is poured into the container the coin will become visible.
This is due to the change in the apparent position of the coin. When water is poured into the glass container, the light rays from the coin will have to travel through more than one medium and thereby undergoing refraction. Due to refraction, the position of the coin seems to be shifted slightly upwards and the coin becomes visible.
